[jira] [Commented] (SOLR-14300) Some conditional clauses on
unindexed field will be ignored by query parser in some specific cases
[ https://issues.apache.org/jira/browse/SOLR-14300?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17049940#comment-17049940 ]
KOUTA SETSU commented on SOLR-14300:
------------------------------------
our team did a little bit research, and we wander if it is a bug of SolrQueryParser.
more specifically, we think if statement here might be wrong.
{code:java}
// If this field isn't indexed, or if it is indexed and we want to use TermsQuery, then collect this value.
// We are currently relying on things like PointField not being marked as indexed in order to bypass
// the "useTermQuery" check.
if ((fieldValues == null && useTermsQuery) || !sfield.indexed()) {
fieldValues = new ArrayList<>(2);
fmap.put(sfield, fieldValues);
}
{code}
[https://github.com/apache/lucene-solr/blob/branch_8_4/solr/core/src/java/org/apache/solr/parser/SolrQueryParserBase.java#L711]
this if statement will cause fieldValues to be overwritten if sfiled is not indexed.
we will do more research and try to fix this problem.
but we need a little more time because we need our company's permission.
thanks.

> Key: SOLR-14300
> URL: https://issues.apache.org/jira/browse/SOLR-14300
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: query parsers
> Affects Versions: 7.3.1
> Environment: Solr 7.3.1
> centos7.5
> Reporter: KOUTA SETSU
> Priority: Minor
>
> In some specific cases, some conditional clauses on unindexed field will be ignored
> * for query like, q=A:1 OR B:1 OR A:2 OR B:2
> if field B is not indexed(but docValues="true"), "B:1" will be lost.
>
> * but if you write query like, q=A:1 OR A:2 OR B:1 OR B:2,
> it will work perfect.
> the only difference of two queries is that they are wrote in different orders.
> one is *ABAB*, another is *AABB.*
>
> *steps of reproduce*
> you can easily reproduce this problem on a solr collection with _default configset and exampledocs/books.csv data.
> # create a _default collection
> {code:java}
> bin/solr create -c books -s 2 -rf 2{code}
> # post books.csv.
> {code:java}
> bin/post -c books example/exampledocs/books.csv{code}
> # run followed query.
> ** query1: [http://localhost:8983/solr/books/select?q=+(name_str:Foundation+OR+cat:book+OR+name_str:Jhereg+OR+cat:cd)&debug=query]
> ** query2: [http://localhost:8983/solr/books/select?q=+(name_str:Foundation+OR+name_str:Jhereg+OR+cat:book+OR+cat:cd)&debug=query]
> ** then you can find the parsedqueries are different.
