> 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.)
