Is it possible to highlight whole query terms? f.e. when I ask for "United States" I want to get:
<em>United States</em>
and not:
<em>United</em> <em>States</em>
I've searched the whole Internet for an answer, used all combinations of hl.mergeContiguous, hl.usePhrasesHighlighter and hl.highlightMultiTerm parameters and still cannot make it work.
my query is:
http://localhost:8983/solandra/idxPosts.proj350_139/select?q=post_text:"Janusz Palikot"&hl=true&hl.fl=post_text&hl.mergeContiguous=true&hl.usePhrasesHighlighter=true&hl.highlightMultiTerm=true
the answer is:
...
<arr name="post_text"><str>Tag: <em>janusz</em> <em>palikot</em> - Sowiniec: "Sowiniec"</str></arr>
...
my "post_text" field is:
<field name="post_text" type="text" indexed="true" stored="true" termVectors="true" termPositions="true" termOffsets="true" required="true" />
my "text" type is:
<fieldType name="text" class="solr.TextField">
<analyzer type="index">
<tokenizer class="solr.StandardTokenizerFactory" />
<filter class="solr.TrimFilterFactory" />
<filter class="solr.LowerCaseFilterFactory" />
<filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords_pl.txt" />
<filter class="solr.ReversedWildcardFilterFactory" />
</analyzer>
<analyzer type="query">
<tokenizer class="solr.StandardTokenizerFactory" />
<filter class="solr.TrimFilterFactory" />
<filter class="solr.LowerCaseFilterFactory" />
<filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords_pl.txt" />
</analyzer>
</fieldType>
I also tried to use FastVectorHighlighter with hl.useFastVectorHighlighter=true but encountered an error:

Can you help me, please?
