Jan Høydahl commented on SOLR-6113:
-----------------------------------
Suggestion for improvements welcome. In my opinion, simply discarding the whole
term is also very confusing. Imagine {{uf=-title&q=title:java language}} -> as
we're now you will require the three words title, java, language. If we remove
the first term we'll match all docs with "language", clearly not the intention.
A perhaps better solution could be to search literally for the string
"title:java" instead of breaking it into two?
Alternatively, disregard the "field" part, but let the value part stay and be
subject to qf or df. However, that could be confusing too, if the user won't
get any feedback whatsoever that his query term "java" was actually not
restricted to title only.

> Key: SOLR-6113
> URL: https://issues.apache.org/jira/browse/SOLR-6113
> Project: Solr
> Issue Type: Bug
> Components: query parsers
> Reporter: Liram Vardi
> Labels: edismax
>
> It seems that Edismax User Fields feature does not behave as expected.
> For instance, assuming the following query:
> _"q= id:b* user:"Anna Collins"&defType=edismax&uf=* -user&rows=0"_
> The parsed query (taken from query debug info) is:
> _+((id:b* (text:user) (text:"anna collins"))~1)_
> I expect that because "user" was filtered out in "uf" (User fields), the
> parsed query should not contain the "user" search part.
> In another words, the parsed query should look simply like this: _+id:b*_
> This issue is affected by a the patch on issue SOLR-2649: When changing the
> default OP of Edismax to AND, the query results change.
