Re: Solr query help

[Tim Casey]

You can add a ~3 to the query to allow the order to be reversed, but you
will get extra hits.  Maybe it is a ~4, i can never remember on phrases and
reversals.  I usually just try it.

Alternatively, you can create a custom query field for what you need from
dates.  For example, if you want to search by queries like "fourth
tuesday", you need to have 'tuesday" in a query and better to have " 4
tuesday " as part of the field.

Instead of a phrase query, you do +2017 +(04 03) +(01 02 03 04 05 06 07 08
09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31),
which does all the days in march and apr.  A more complicated nested query
would do more complicated date ranges.

I don't know if there is a way to get repeating date range queries, like
the fourth tuesday for all months in a year.  The date support is usually
about querying a specified range at a time.

Re: Solr query help

[Nawab Zada Asad Iqbal]

Hi Krishna

I haven't used date range queries myself. But if Solr only supports a
particular date format, you can write a thin client for queries, which will
convert the date to solr's format and query solr.

Solr query help

[chiru s]

Hello guys

I am working on Apache solr and I am stuck with a use case.


The input data will be in the documents like 2017/03/15 in 1st document,

2017/04/15 in 2nd doc,

2017/05/15 in 3rd doc,

2017/06/15 in 4th doc so on

But while fetching the data it should fetch like 03/15/2017 for the first
doc and so on.

My requirement is like this ..


The data is like above and when I do an fq with name:[2017/03/15 TO
2017/05/15] it fetches me the 1st three documents.. but the need the data
as 03/15/2017 instead of 2017/03/15.


I tried solr.pattetnReplaceCharFilterFactory but it doesn't seem working..

Can you please help on the above.


Thanks in advance

Are those asterisks in your actual query, or did you add some of them
for emphasis?  I'm guessing that at least some of them are added for
emphasis.  Asterisks in a query are wildcard characters, and wildcard
queries frequently do not behave like people expect them to.

We need to see the actual query, without any extra characters.  If
asterisks have been added, then we will have an incorrect understanding
about what the query says.

Attempting to guess what you are actually doing, here is what I THINK
you might have meant:

q=blood
fq=id:(939 OR *)

If I'm right about that filter query, I do not know what you were trying
to do.  If you were trying to query for 939 or any other value, use this
instead:

fq=id:[* TO *]

This is a range query that will match all documents where the id field
contains SOMETHING.  Documents where it is not present will not be
matched.  If you do not actually want to *filter* on the id value, then
you can simply remove the fq parameter entirely.  Filter queries do not
contribute to scoring at all -- they *only* filter.

The last part of your message says you want documents with an id of 939
to be listed first.  I think you can do that with this:

bq=id:939^10

The bq parameter means "boost query".  The ^10 part of what I've written
is the boost value.

Thanks,
Shawn

Re: Need solr query help

[Amit Nithian]

Is it possible instead to store in your solr index a bounding box of store
location + delivery radius, do a bounding box intersection between your
user's point + radius (as a bounding box) and the shop's delivery bounding
box. If you want further precision, the frange may work assuming it's a
post-filter implementation so that you are doing heavy computation on a
presumably small set of data only to filter out the corner cases around the
radius circle that results.

I haven't looked at Solr's spatial querying in a while to know if this is
possible or not.

Cheers
Amit

Re: Need solr query help

[smsolr]

Hi Abhishek,

I forgot to explain why it works.  It uses the frange filter which is
mentioned here:-

http://wiki.apache.org/solr/CommonQueryParameters

and it works because it filters in results where the geodist minus the
shopMaxDeliveryDistance is less than zero (that's what the u=0 means, upper
limit=0), i.e.:-

geodist - shopMaxDeliveryDistance < 0
->
geodist < shopMaxDeliveryDistance

i.e. the geodist is less than the shopMaxDeliveryDistance and so the shop is
within delivery range of the location specified.

Re: Need solr query help

[smsolr]

Hi Abhishek,

I've had a look into this problem and have come up with a solution.

Following instructions assume you have downloaded the 4.3.0 release of Solr
from:-

http://www.apache.org/dyn/closer.cgi/lucene/solr/4.3.0

First add to:-

solr-4.3.0/solr/example/solr/collection1/conf/schema.xml

the following:-

   
   

after the id field:-



Then start solr by going to:-

solr-4.3.0/solr/example

and running:-

java -jar start.jar

Then change into your solr-4.3.0/solr/example/exampledocs directory and
write the following text to a new file called shops.xml:-



2468
Shop A
   0.1,0.1
   10


2469
Shop B
   0.2,0.2
   35


2470
Shop C
   0.9,0.1
   25


2480
Shop D
   0.3,0.2
   50




Now run:-

./post.sh shops.xml 

You should get back something like:-


Posting file shops.xml to http://localhost:8983/solr/update


0120




046



The doing the following queries in your browser:-

All 4 shops:-

http://localhost:8983/solr/select?q=name:shop&fl=name,shopLocation,shopMaxDeliveryDistance


All shops with distance from point 0.0,0.0 and ordered by distance from
point 0.0,0.0 (gives order A, B, D, C):-

http://localhost:8983/solr/select?q=name:shop&fl=name,shopLocation,shopMaxDeliveryDistance,geodist%28shopLocation,0.0,0.0%29&sort=geodist%28shopLocation,0.0,0.0%29%20asc


All shops with distance from point 0.0,0.0 and ordered by distance from
point 0.0,0.0 and filtered to eliminate all shops with distance from point
0.0,0.0 greater than shopMaxDeliveryDistance (gives shops  B and D):-

http://localhost:8983/solr/select?q=name:shop&fl=name,shopLocation,shopMaxDeliveryDistance,geodist%28shopLocation,0.0,0.0%29&sort=geodist%28shopLocation,0.0,0.0%29%20asc&fq={!frange%20u=0}sub%28geodist%28shopLocation,0.0,0.0%29,shopMaxDeliveryDistance%29


To delete all shops so you can edit the file to play with it and repost the
shops:-

http://localhost:8983/solr/update?stream.body=name:shop&commit=true

Need solr query help

[Abhishek tiwari]

We are doing spatial search. with following logic.
a) There are shops in a city . Each provides the facility of home delivery
b) each shop has different  max_delivery_distance .

Now my query is suppose some one is searching from point P1 with radius R.

User wants the result of shops those can deliver him.(distance between P1
to shop s1 say d1 should be less than max_delivery distance say md1 )

how can i implement this by solr spatial query.

I am working on one project which is used solr search facilities and its

I search color just for example :

In that query I want pass another color like "Red" with both condition

Hi, I have a field called firstLetterTitle, this field has 1 char, it  
can be anything, I need help with a few queries on this char:


1.) I want all NON ALPHA and NON numbers, so any char that is not A-Z  
or 0-9


I tried:

http://localhost:8983/solr/select?q=NOT%20firstLetterTitle:0%20TO%209%20AND%20NOT%20firstLetterTitle:A%20TO%20Z

But I get back numeric results:


9
23946447



2.) I want all only Numerics:

http://localhost:8983/solr/select?q=firstLetterTitle:0%20TO%209

This seems to work but just checking if its the right way.



2.) I want all only English Letters:

http://localhost:8983/solr/select?q=firstLetterTitle:A%20TO%20Z

This seems to work but just checking if its the right way.


thanks
Joel

Re: Solr Query help - sorting

[Erik Earle]

I am indexing my data both through DataImportHandler and per transaction from 
JPA using @PostXXX listeners. 

UpdateRequestProcessor looks like exactly what I need I don't suppose 
there's a scriptable subclass available in 1.4 that is configured from 
schema.xml?   :-)

Thanks guys!

If you're using DataImportHandler, a custom (Java or script)  
transformer could do this.

Also an UpdateProcessor could do it.

But there is no conditional copyField capabilities otherwise.

Keep in mind that pragmatically, if you're doing your own indexing  
code, why not have a line like this?  :)

max_side = (length > width) ? length : width

I'd like to push as much of this into Solr as I can because the app  
and db that Solr is indexing are not really the best place to add  
this type of functionality.

You couldn't sort on a multiValued field though.

I'd simply index a max_side field, and have the indexing client add a  
single valued field with max(length,width) to it.  Then sort on  
max_side.

Clever... but if more than one row adds up to the same value I may get the

I need a max function but the one provided only compares against a constant.
