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?
Highlighting in Solr allows fragments of documents that match the user's query to be included with the query response.
Faceting is the arrangement of search results into categories based on indexed terms. Searchers are presented with the indexed terms, along with numerical counts of how many matching documents were found were each term.
For the phrase highlight, there is a Jira stilling waiting to get through to the Solr code.
