If I do a query for a couple of words in quotes, Solr correctly only returns pages where those words appear exactly within the quotes. But the highlighting acts as if the words were given separately, and stems them and everything. For example, if I search for "knee pain", it returns a document that has the word "knee pain", and doesn't return documents that have "knee" and "pain" without other words between them. However, with highlighting turned on, the highlighted field will have "knee", "knees", "pain" and "pains" highlighted even when they aren't next to each other. For instance: <response><lst name='responseHeader'><int name='status'>0</int> <int name='QTime'>45</int> <lst name='params'><str name='explainOther'/> <str name='fl'>*,score</str> <str name='indent'>on</str> <str name='start'>0</str> <str name='q'>"knee pain"</str> <str name='hl.fl'>text</str> <str name='qt'>standard</str> <str name='wt'>standard</str> <str name='hl'>on</str> <str name='rows'>10</str> <str name='version'>2.2</str> </lst> </lst> .... <lst name='2: http://news.prnewswire.com/DisplayReleaseContent.aspx?ACCT=ind_focus.story&STORY=/www/story/09-24-2009/0005100306&EDATE= '><arr name='text'><str>I had one injection in each <em>knee</em> and my doctor said it could relieve my <em>knee</em> <em>pain</em> for up to six</str> </arr> </lst>
