      Description

      When matching strings that do not include alphanumeric chars, all the data is returned as matches. (There is actually no match, so nothing should be returned.)

      When I run a query like - (activity_type:NAME) AND title!@#$%^&*()) all the documents are returned even though there is not a single match. There is no title that matches the string (which has been escaped).

      My document structure is as follows

      <doc>
      <str name="activity_type">NAME</str>
      <str name="title">Bathing</str>
      ....
      </doc>

      The title field is of type text_title which is described below.

      <fieldType name="text_title" class="solr.TextField" positionIncrementGap="100">
      <analyzer type="index">
      <tokenizer class="solr.WhitespaceTokenizerFactory"/>
      <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="1" splitOnCaseChange="1"/>
      <filter class="solr.LowerCaseFilterFactory"/>
      <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
      </analyzer>
      <analyzer type="query">
      <tokenizer class="solr.WhitespaceTokenizerFactory"/>
      <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
      <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="1" splitOnCaseChange="1"/>
      <filter class="solr.LowerCaseFilterFactory"/>
      <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>

      </analyzer>
      </fieldType>

      -----------------------------------------------------
      Yonik's analysis as follows.

      <str name="rawquerystring">-features:foo features!@#$%^&*())</str>
      <str name="querystring">-features:foo features!@#$%^&*())</str>
      <str name="parsedquery">-features:foo</str>
      <str name="parsedquery_toString">-features:foo</str>

      The text analysis is throwing away non alphanumeric chars (probably
      the WordDelimiterFilter). The Lucene (and Solr) query parser throws
      away term queries when the token is zero length (after analysis).
      Solr then interprets the left over "-features:foo" as "all documents
      not containing foo in the features field", so you get a bunch of
      matches.

      As per his suggestion, a bug is filed.
