Solr query with grouping not working <p>The following query works fine:</p> <pre><code>q=field_one:value_one AND -field_two:[* TO *] AND -field_three:[* TO *] </code></pre> <p>However, as soon as I put brackets in there I get no results</p> <pre><code>q=field_one:value_one AND (-field_two:[* TO *] AND -field_three:[* TO *]) </code></pre> <p>Aren't these two queries equivalent?</p> <p>Thanks all</p> <p><em>Dave</em></p> <p>NB: I'm doing this as I need to combine more 'AND's with 'OR's; rather than just because I like brackets.</p>
