Re: Replication snapshot, tar says "file changed as we read it"

[Andrew Clegg]

Sorry to re-open an old thread, but this just happened to me again,
even with a 30 second sleep between taking the snapshot and starting
to tar it up. Then, even more strangely, the snapshot was removed
again before tar completed.

Archiving snapshot.20110320113401 into
/var/www/mesh/backups/weekly.snapshot.20110320113401.tar.bz2
tar: snapshot.20110320113401/_neqv.fdt: file changed as we read it
tar: snapshot.20110320113401/_neqv.prx: File removed before we read it
tar: snapshot.20110320113401/_neqv.fnm: File removed before we read it
tar: snapshot.20110320113401: Cannot stat: No such file or directory
tar: Exiting with failure status due to previous errors

Has anybody seen this before, or been able to replicate it themselves?
(no pun intended)

Or, is anyone else using replication snapshots for backup? Have I
misunderstood them? I thought the point of a snapshot was that once
taken it was immutable.

If it's important, this is on a machine configured as a replication
master, but with no slaves attached to it (it's basically a failover
and backup machine).

Re: Solr coding

[satya swaroop]

Hi Jayendra,
  the group field can be kept if the no. of groups are
small... if a user may belong to 1000 groups in that case it would be
difficult to make a query???,   if a user changes the groups then we have to
reindex the data again...

ok i will try ur suggestion, if it can fulfill the needs then task will be
very easy...

how to run boost query for non-dismax query parser

[cyang2010]

Hi,

I need to code some boosting logic when some field equal to some value.   I
was able to get it work if using dismax query parser.  However, since the
solr query will need to handle prefix or fuzzy query, therefore, dismax
query parser is not really my choice.  

Therefore, i want to use standard query parser, but still have dismax's
boosting query logic.  For example, this query return all the titles
regardless what the value is, however, will boost the score of those which
genres=5237:

http://localhost:8983/solr/titles/select?indent=on&start=0&rows=10&fl=*%2Cscore&wt=standard&explainOther=&hl.fl=&qt=standard&q={!boost%20b=genres:5237^2.2}*%3A*&debugQuery=on


Here is the exception i get:
HTTP ERROR: 400

org.apache.lucene.queryParser.ParseException: Expected ',' at position 6 in
'genres:5237^2.2'


I am just following the instruction on this page although the instruction
there is really to implement a boost function, instead of boosting query. 
http://wiki.apache.org/solr/SolrRelevancyFAQ#How_can_I_boost_the_score_of_newer_documents

Thanks for your help,

cy

Re: dismax parser, parens, what do they do exactly

[Chris Hostetter]

: It looks like Dismax query parser can somehow handle parens, used for
: applying, for instance, + or - to a group, distributing it. But I'm not
: sure what effect they have on the overall query.

parens are treated like any regular character -- they have no semantic 
meaning.

what may be confusing you is what the *analyzer* you have configured for 
your query field then does with the paren.

For instance, using the example schema on trunk, try the same query...

q = book (dog +(cat -frog))

..but using a "qf" param containing a string field (no analysis) ...

/select?defType=dismax&q=book+(dog+%2B(cat+-frog))&tie=0.01&qf=text_s&debugQuery=true

It produces the following output (i've added some whitespace)...


 +(  DisjunctionMaxQuery((  text_s:book)~0.01) 
 DisjunctionMaxQuery((  text_s:(dog)~0.01) 
+DisjunctionMaxQuery((  text_s:(cat)~0.01) 
-DisjunctionMaxQuery((  text_s:frog))  )~0.01)
  ) 
  ()


...the parens from your query are being treated literally as characters in 
your terms.  you just don't see them in the parsed query because it shows 
you what those terms look like after the anlsysis.

Incidently...

: debugQuery shows:
: 
: +((DisjunctionMaxQuery((text:book)~0.01)
: +DisjunctionMaxQuery((text:dog)~0.01)
: DisjunctionMaxQuery((text:cat)~0.01)
: -DisjunctionMaxQuery((text:frog)~0.01))~2) ()

...double check that, it doesn't seem to match the query string you posted 
(it shows "dog" being mandatory.  i'm guessing you cut/paste the wrong 
example)

Why boost query not working?

[cyang2010]

Hi, 

This solr query faile:
1. get every title regardless what the title_name is
2. within the result, boost the one which genre id = 56.  (bq=genres:56^100)

http://localhost:8983/solr/titles/select?indent=on&version=2.2&start=0&rows=10&fl=*%2Cscore&wt=standard&defType=dismax&qf=title_name_en_US&q=*%3A*&bq=genres%3A56^100&debugQuery=on


But from debug i can tell it confuse the boost query parameter as part of
query string:

lst name="debug">
str name="rawquerystring">*:*
str name="querystring">*:*
str name="parsedquery">+() () genres:56^100.0
str name="parsedquery_toString">+() () genres:56^100.0
lst name="explain"/>
str name="QParser">DisMaxQParser
null name="altquerystring"/>
−
arr name="boost_queries">
str>genres:56^100
/arr>
−

genres:56^100.0




Just to note that genres field is a multivalue field.  I don't know if
boosting query has any requirement on single value/token.

But i also tried with another single value query field for bq, similar
problem:

http://localhost:8983/solr/titles/select?indent=on&version=2.2&q=*%3A*&fq=&start=0&rows=10&fl=*%2Cscore&wt=standard&explainOther=&hl.fl=&defType=dismax&qf=title_name_en_US&bq=year[2000
TO *]^2.2&debugQuery=on


Thanks for you help,

cy

Re: Search failing for matched text in large field

Enable TermVectors for fields that you're going tot highlight. If it is

Re: Search failing for matched text in large field

[Jonathan Rochkind]

Yeah, you aren't going to be able to do highlighting on a very very 
large field without terrible performance.  I believe it's just the 
nature of the algorithm used by the highlighting component. I don't know 
of any workaround.  Other than inventing a new algorithm for 
highlighting and writing a component for it.


Even with an AJAX call, you don't want to wait 3 minutes. Plus the load 
on your server.

The field in question needs to be stored=true, because it is needed

Storing Nested Fields

[Sethi, Parampreet]

Hi All,

This is regarding nested array functionality. I have requirements
1. to store category and sub-category association with a word in the Solr.
2. Also each word can be listed under multiple categories (and thus
sub-categories). 
3. Query based on category or sub-category.

One way is to have two separate Array fields in Solr and making sure that
field category[0] is the super-category of field sub-category[0].

Has anyone encountered similar problem in Solr? Any suggestions will be
great.

Thanks

Re: Solr performance issue

[Doğacan Güney]

Hello,

The problem turned out to be some sort of sharding/searching weirdness. We
modified some code in sharding but I don't think it is related. In any case,
we just added a new server that just shards (but doesn't do any searching /
doesn't contain any index) and performance is very very good.

Thanks for all the help.

Re: Search failing for matched text in large field

[Jonathan Rochkind]

Hmm, there's no reason it should take anywhere close 3 minutes to get a 
result from a simple search, even with very large documents/term lists.  
Especially if you're really JUST doing a simple search, you aren't using 
facetting or statistics component or highlighting etc at this point. (If 
you ARE using highlighting, that could be the culprit).


You might need more RAM allocated to the Solr JVM.  For reasons I can't 
explain myself, I sometimes get pathologically slow search results when 
I don't have enough RAM, even though there aren't any errors in my logs 
or anything -- which adding more RAM fixes.


It's also possible (just taking random guesses, I am not familiar with 
this part of Solr internals), that if you increased the maxFieldLength 
on an existing index, but only reindexed SOME of the results in that 
index, than Solr is getting all confused about your index. I don't know 
if Solr can handle changing the maxFieldLength on an existing index 
without re-indexing all docs.


Also, if you tell us HOW large you made maxFieldLength, someone (not me) 
might be able to say something about if it's so large it could create 
some kind of other problem.

Brian, I think best thing to do is checkout a new clean copy from subversion 
and then do things step by step on this clean copy.


  

Re: Search failing for matched text in large field

[Paul]

I increased maxFieldLength and reindexed a small number of documents.
That worked -- I got the correct results. In 3 minutes!

I assume that if I reindex all my documents that all searches will
become even slower. Is there any way to get all the results in a way
that is quick enough that my user won't get bored waiting? Is there
some optimization of this coming in solr 3.0?

Re: Solr coding

[Jayendra Patil]

In that case, you may want to store the groups as multivalued fields
who would have access to the document.
A filter query on the user group should have the results filtered as
you expect.

you may also check Apache ManifoldCF as suggested by Szott.

Re: multifield search using dismax

[Jonathan Rochkind]

It is not.  I think it is is possible in edismax, on trunk (not yet in a 
released version, not sure if it will be in the upcoming release).


Alternately, you can use Solr nested queries, although they're not 
really suitable for end-user-entry, and you might lose the behavior of 
dismax you want, depending on what behavior you want.


&defType=lucene
&q=_query_:"{!dismax qf='field1 field2'}value1" AND _query_:"{!dismax 
qf='field3 field4'}more values"

Re: Search failing for matched text in large field

How large?

But rather than think about if there's something in the "searching" 
that's not working, the first step might be to make sure that everything 
in the _indexing_ is working -- that your field is actually being 
indexed as you intend.


I forget the best way to view what's in your index -- the Luke request 
handler in the Solr admin maybe?

Ah, no, I'll try that now.

What is the disadvantage of setting that to a really large number?

I do want the search to work for every word I give to solr. Otherwise
I wouldn't have indexed it to begin with.

Re: Solr coding

[satya swaroop]

Hi Jayendra,
I forgot to mention the result also depends on the group of
user too It is some wat complex so i didnt tell it.. now i explain the
exact way..

  user1, group1 -> java1, c1,sap1
  user2 ,group2-> java2, c2,sap2
  user3 ,group1,group3-> java3, c3,sap3
  user4 ,group3-> java4, c4,sap4
  user5 ,group3-> java5, c5,sap5

 user1,group1 means user1 belong to group1


Here the filter includes the group too.., if for eg: user1 searches for
"java" then the results should show as java1,java3 since java3 file is
acessable to all users who are related to the group1, so i thought of to
edit the code...

Thanks,

Why not just add an extra field to the document in the Index for the
user, so you can easily filter out the results on the user field and
show only the documents submitted by the User.

Re: Solr - multivalue fields - please help

[Jayendra Patil]

Just a suggestion ..
You can try using dynamic fields by appending the company name (or ID)
as prefix ... e.g.

For data -
Employee ID Employer FromDate ToDate
21345
IBM 01/01/04 01/01/06
MS 01/01/07 01/01/08
BT 01/01/09 Present

Index data as :-
Employee ID - 21345
Employer Name - IBM MS BT (Multivalued fields)
IBM_FROM_DATE - 01/01/04 (Dynamic field)
IBM_TO_DATE - 01/01/06 (Dynamic field)

You should be able to match the results and get the from and to date
for the companies and handle it on UI side.

Jayendra

Solr - multivalue fields - please help

[Sandra]

Hi everyone,

I know that Solr cannot match 1 value in a multi-valued field with
the corresponding value in another multi-valued field. However my data set
appears to be in that form at the moment.
With that in mind does anyone know of any good articles or
discussions that have addressed this issue, specifically the alternatives
that can be easily done/considered etc

The data is of the following format:

I have an unique Employee ID field, Employer (multi-value), FromDate
(multi-value) amd ToDate (multi-value). For a given employee ID I am trying
to return the relevent data. For example for a ID of "21345" and emplyer
"IMB" return the work dates from and to. Or for same id and 2 work dates
return the company of companies that the id was associated with etc


Employee ID Employer FromDate ToDate
21345 IBM 01/01/04 01/01/06
MS 01/01/07 01/01/08
BT 01/01/09 Present 

Any suggestions/comments/ideas/articles much appreciated...

RE: Architecture question about solr sharding

[Baillie, Robert]

I'd separate the splitting of the binary documents from the sharding in Solr - 
they're different things and the split may be required at different levels, due 
to different numbers of documents.

Splitting the dependency means that you can store the path in the document and 
not need to infer anything, and you can re-organise the Solr shards without 
having to worry about moving the binary documents around.

Also, if you think you're going to need to change Jan to Jan2011, then maybe 
you should just start with Jan2011.  Alternatively, considering that you think 
change is likely in the future, why not name the directories in such a way that 
you don't need to make the change earlier ones as the requirement to change the 
structures arises?

Does that make sense?

Unknown query type 'edismax'

[Swapnonil Mukherjee]

Hi,

I just downloaded apache-solr-1.4.1 and am trying to run an edismax query using 
the defType argument as edismax.

But I am setting an Unkown query type exception.

Do I need to make any changes to solrconfig.xml to get edismax queries to work?
