Is it possible to use the Lucene Query Builder? Is there any API to create boolean queries?

[email]

I am trying to simulate the following query(Lucene query builder) using Solr


 

BooleanQuery.Builder main = new BooleanQuery.Builder();

Term t1 = new Term("f1","term");
Term t2 = new Term("f1","second");
Term t3 = new Term("f1","another");

BooleanQuery.Builder q1 = new BooleanQuery.Builder();
q1.add(new FuzzyQuery(t1,2), BooleanClause.Occur.SHOULD);
q1.add(new FuzzyQuery(t2,2), BooleanClause.Occur.SHOULD);
q1.add(new FuzzyQuery(t3,2), BooleanClause.Occur.SHOULD);
q1.setMinimumNumberShouldMatch(2);

Term t4 = new Term("f1","anothert");
Term t5 = new Term("f1","anothert2");
Term t6 = new Term("f1","anothert3");

BooleanQuery.Builder q2 = new BooleanQuery.Builder();
q2.add(new FuzzyQuery(t4,2), BooleanClause.Occur.SHOULD);
q2.add(new FuzzyQuery(t5,2), BooleanClause.Occur.SHOULD);
q2.add(new FuzzyQuery(t6,2), BooleanClause.Occur.SHOULD);
q2.setMinimumNumberShouldMatch(2);


main.add(q1.build(),BooleanClause.Occur.SHOULD);
main.add(q2.build(),BooleanClause.Occur.SHOULD);
main.setMinimumNumberShouldMatch(1);

System.out.println(main.build()); // (((f1:term~2 f1:second~2
f1:another~2)~2) ((f1:anothert~2 f1:anothert2~2 f1:anothert3~2)~2))~1   -->
Invalid Solr Query

 

 

In a few words :  ( q1 OR q2 )

 

Where q1 and q2 are a set of different terms using I'd like to do a fuzzy
search but I also need a minimum of terms to match. 

 

The best I was able to create was something like this  : 

 

SolrQuery query = new SolrQuery();
query.set("fl", "term");
query.set("q", "term~1 term2~2 term3~2");
query.set("mm",2);

System.out.println(query);

 

And I was unable to find any example that would allow me to do the type of
query that I am trying to build with only one solr query. 

 

Is it possible to use the Lucene Query builder with Solr? Is there any way
to create Boolean queries with Solr? Do I need to build the query as a
String? If so , how do I set the mm parameter in a String query? 

 

Thank you

Now one company thinks I’m after them because they were the main source of
the jokes.

Companies is not a typo.

If you are using Solr to make or save tons of money or run your business
and you employee developers, please include yourself in this list.

You are taking and in my opinion Solr is going down. It’s all against your
own interest even.

I know of enough people that want to solve this now, that it’s likely only
a matter of time before they fix the situation - you ever know though.
Things change, people get new jobs, jobs change. It will take at least 3-6
months to make things reasonable even with a good group banding together.

But if you are extracting value from this project and have Solr developers
- id like to think you have enough of a stake in this to think about
changing the approach everyone has been taking. It’s not working, and the
longer it goes on, the harder it’s getting to fix things.

Re: Backup v.s. Snapshot API for Solr

[Kayak28]

Hello, Mr. Paras and Community Members:

>Once you have created a snapshot with
>CREATESNAPSHOT, you can restore the snapshot with same replication restore
>command, right?

Is it?

As far as I know,
CREATESNAPSHOT is an action to create a file, named snapshot_N, under
data/snapshot_metadata directory.

The snapshot_N is a binary file, which contains the path to the index and
the commit name you defined like below.


> ?×l solr-snapshots
> commit1:/home/vagrant/solr-7.4.0/server/solr/core1/data/index/
>
commit1 is the commit name I named and /home/vagrant/ is the path to my
index.

My question is,  having the path to the index and the commit name, how is a
snapshot possible to restore my index?
Or is the CREATESNAPSHOT command only available for Solr Cloud mode?
(whereas my case is standalone)

I should try with SolrCloud Mode later.
Then, I wll execute CREATESNAPSHOT and restore command, let's see if I can
really restore my index on CloudMode.
I only played with a standalone mode.

Re: A Last Message to the Solr Users

[Walter Underwood]

I’m a big fan of master/slave Solr. Super robust and trivial to scale-out.

Solr Cloud has been useful for managing sharding and replicas, but less robust 
than I would like. Also less robust than my managers would like. It has gotten 
a bad reputation, only partially undeserved.

I’m also not especially impressed with the Solr community openness to changes 
from outside of the committers. At some point, I’ll do the fourth port of a 
small enhancement to edismax. I’d love to run stock Solr, but I can’t. Fuzzy 
search got 100X faster in 4.x, but it isn’t available in edismax, even though 
it makes a huge difference for misspelled queries.

Want to make a change that radically improves basic search? Implement IDF for 
phrases. Infoseek used that to beat Google in relevance for years. The patent 
has expired, so go for it.

Also, how about a free text parser so we don’t have to rip out all the Lucene 
syntax in queries?

Convert javabin to json

[Wei]

Hi,

Is there a reliable way to convert solr's javabin response to json format?
We use solrj client with wt=javabin, but want to convert the received
javabin response to json for passing to client.  We don't want to use
wt=json as javabin is more efficient.  We tried the noggit jsonutil

https://github.com/apache/lucene-solr/blob/master/solr/solrj/src/java/org/noggit/JSONUtil.java

but seems it is not able to convert parts of the query response such as
facet.  Are there any other options available?

Thanks,
Wei

Even if that works, it is evil as something to leave in a client codebase. 
Maybe a do-no-overwrite flag would be useful.

How about Optimistic Concurrency with _version_ set to negative value?

You could inject that extra value in URP chain if need be.

Prevent Solr overwriting documents

[Aaron Hoffer]

We want to prevent Solr from overwriting an existing document if document's
ID already exists in the core.

This unit test fails because the update/overwrite is permitted:

public void testUpdateProhibited() {
  final Index index = baseInstance();
  indexRepository.save(index);
  Index index0 = indexRepository.findById(INDEX_ID).get();
  index0.setContents("AAA");
  indexRepository.save(index0);
  Index index1 = indexRepository.findById(INDEX_ID).get();
  assertThat(index, equalTo(index1));
}


The failure is:
Expected: 
but: was 

What do I need to do prevent the second save from overwriting the existing
document?

I commented out the updateHandler in the solr config file, to no effect.
We are using Spring Data with Solr 8.1.
In the core's schema, id is defined as unique  like this:
id

The index looks like it's corrupt.  It's missing at least one of its files.

If you have deleted the index, then you must also delete the index 
directory itself.  If the index directory exists and is empty, Lucene 
will be unable to open it.

Re: A Last Message to the Solr Users

[Mark Miller]

If SolrCloud worked well I’d still agree both options are very valid
depending on your use case. As it is, I’m embarrassed that people give me
any credit for this. I’m here to try and delight users and I have failed in
that. I tried to put a lot of my own time to address things outside of
working on my job of integrating Hadoop and upgrading Solr 4 instances for
years. But I couldn’t convince anyone of what was necessary to address what
has been happening, and my paid job has always been doing other things
since 2012.

Did you happen to check the permissions , give it a try to add 777, maybe
the user running solr does not have permission to access the index dir.

Hi,

I removed the write.lock file from the index and then restarted the solr

It seems to be either the permission problem or maybe because of the write.lock

Re: Icelandic support in Solr

If I’m not mistaken Hunspell supports Icelandic (see here:

HunspellStemFilter should be able to use these dictionaries.

Hmmm... I tried that as well, but it doesn't pick up the security.json

I run this instance on a computer that is on the internet, so just changing

Looks like nobody knows how to import imap data

Re: Production Issue: cannot connect to solr server suddenly

[Vignan Malyala]

Sure!

Error:
Failed to connect to server at '
http://127.0.0.1:8983/solr/my_core/update/?commit=true
',
are you sure that URL is correct? Checking it in a browser might help:
HTTPConnectionPool(host='127.0.0.1', port=8983): Max retries exceeded with
url: /solr/my_core/update/?commit=true (Caused by
NewConnectionError(': Failed to establish a new connection: [Errno 111]
Connection refused',))

I'm using python with pysolr to connect to Solr Instance.
In my production server, I get this issue at certain times in my python
logs while it tries to connect to solr to index data or search results.
When I check the solr UI, it will be working fine, but this issue of solr
refusing to connect at certain times occurs and so my users are not able to
index documents or search data.
Please help with this issue.

Should I increase threads and how to increase threads ? Should I increase
physical memory ?
whats the solution?

Re: Custom sort function

[Sripra deep]

My exact requirement is,  I will have a new field for a set of documents
for sorting. So the number of fields is growing like 10k
fields(custom_sort1,custom_sort2.,etc), for 10k groups, each group grouping
a set of documents. Since the documents can reside in more than one group I
cannot use a single field.
So I tried to use a single field for each document in the format as
"custom_field:group1=1$group2=3". During query time I will filter all the
group1 documents and parse this field and return the respective sort
number.

My solr version is *7.1.0*.

*This is my custom Class:*

public class CustomSortValueSource extends ValueSource{

protected final boolean isasc;
protected final String s1;
protected final ValueSource source;


public CustomSort(ValueSource sources, String s1, String order ) {
if (sources == null || s1 ==null || order == null) {
 throw new SolrException(SolrException.ErrorCode.BAD_REQUEST,
 "One or more inputs missing ");
   }

this.s1 = s1;
this.source = sources;
this.isasc = order.equals("asc") ? true : false;
}

@Override
public FunctionValues getValues(Map context, LeafReaderContext reader)
throws IOException {
final FunctionValues vals = source.getValues(context, reader);
return new FunctionValues() {
   public float floatVal(int doc) {
float toRet = isasc ? Float.MAX_VALUE : Float.MIN_VALUE;
/*
My custom logic in reading a string array and returning a value out
of some condition checks
*/
}
}
}
}

There is nothing happening in the constructor other than assigning.

Thanks,
Sripradeep P

The Snowball stemmer project which is used by Solr 
(https://snowballstem.org/algorithms/ - co-created by Martin Porter, 
author of the famous stemmer) doesn't support Icelandic unfortunately. I 
can't find any other stemmers that you could use in Solr.


Basis Technology offer various commercial software for language 
processing that can work with Solr and other engines, not sure if they 
support Icelandic.


So, not very positive I'm afraid: you could look into creating your own 
stemmer using Snowball, or some heuristic approaches, but you'd need a 
good grasp of the structure of the language.

Maybe can you do it as part of the loading to calculate the score?
Which Solr version are you using? 
Are you doing some heavily lifting into the constructor or your filter?

This is your queue to come and make your jokes with your name attached. I’m

Re: Custom sort function

[Sripra deep]

Hi Jörn Franke,

  I modified the custom function to just return a constant value as 1.0 for
all the docs and ran the load again, the latency is worst like more than
20sec. The filter I am using will fetch 15k documents (so this function is
called 15k times). And if I don't call this function in my query then
latency is less than 10ms.

So it looks like some fundamental issue with this approach and I believe
its been used in many business scenarios. Looking out for what's going
 wrong.

Thanks,
Sripradeep P

A Last Message to the Solr Users

[Mark Miller]

If you have a SolrCloud installation that is somehow working for you,
personally I would never upgrade. The software is getting progressively
more unstable every release.


I wrote most of the core of SolrCloud in a prototype fashion many, many
years ago. Only Yonik’s isolated work is solid and most of my work still
stands as it was. This situation has me abandoning that project so that
people understand I won’t stand by garbage work.

Given that no one seems to understand what is happening in SolrCloud under
the covers or how it was intended to work, their best bet is to start
rewriting. Until they do this, I recommend you do not upgrade from an
install that is working for your needs. A new feature will not be worth the
headaches.


Some of the other committers, who certainly do not understand the scope of
the problem or my code (they would have touched it a bit if they did) would
prefer to laugh or form a defensive posture than fix the situation. Wait
them out. The project will collapse or get better. If I ran a production
instance of SolrCloud, I would wait to see which happens first before
embracing any update.


At this point, the best way to use Solr is as it’s always been - avoid
SolrCloud and setup your own system in standalone mode. If I had to build a
new Solr install today, this is what I would do.


In my opinion, the companies that have been claiming to back Solr and
SolrCloud have been negligent, and all of the users are paying the price.
It hasn’t been my job to work on it in any real fashion since 2012. I’m
sorry I couldn’t help improve the situation for you.


Take it for what it’s worth. To some, not much I’m sure.
