Description

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.

1. create a _default collection

   bin/solr create -c books -s 2 -rf 2

2. post books.csv.

   bin/post -c books example/exampledocs/books.csv

3. 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.)

        "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"}}

     • query2.  ("name_str:Foundation" isn't lost.)

          "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]]))",
