----------------------------------

             Summary: Some conditional clauses on unindexed field will be ignored by query parser in some specific cases
                 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


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.
 *** query1.  ("name_str:Foundation" is lost.)
{code:json}
 "debug":{
     "rawquerystring":"+(name_str:Foundation OR cat:book OR name_str:Jhereg OR cat:cd)",
     "querystring":"+(name_str:Foundation OR cat:book OR name_str:Jhereg OR cat:cd)",
     "parsedquery":"+(cat:book cat:cd (name_str:[[4a 68 65 72 65 67] TO [4a 68 65 72 65 67]]))",
     "parsedquery_toString":"+(cat:book cat:cd name_str:[[4a 68 65 72 65 67] TO [4a 68 65 72 65 67]])",
     "QParser":"LuceneQParser"}}{code}

 *** query2.  ("name_str:Foundation" isn't lost.)
{code:json}
   "debug":{
     "rawquerystring":"+(name_str:Foundation OR name_str:Jhereg OR cat:book OR cat:cd)",
     "querystring":"+(name_str:Foundation OR name_str:Jhereg OR cat:book OR cat:cd)",
     "parsedquery":"+(cat:book cat:cd ((name_str:[[46 6f 75 6e 64 61 74 69 6f 6e] TO [46 6f 75 6e 64 61 74 69 6f 6e]]) (name_str:[[4a 68 65 72 65 67] TO [4a 68 65 72 65 67]])))",
     "parsedquery_toString":"+(cat:book cat:cd (name_str:[[46 6f 75 6e 64 61 74 69 6f 6e] TO [46 6f 75 6e 64 61 74 69 6f 6e]] name_str:[[4a 68 65 72 65 67] TO [4a 68 65 72 65 67]]))",
     "QParser":"LuceneQParser"}{code}
