You are not using a string type, but a TextField. And in your analysis chain,
standardtokenizer strips the number sign (or #). You can check this in the
"analysis" part
of the solr backend.
You can either use a string type for seaches like C#, C++ and the like, or map
the
characters to something textual *before* tokenizing. My solution goes something
like this:
<charFilter class="solr.MappingCharFilterFactory" mapping="mapping-chars.txt"/>
while mapping-chars.txt is:
*****************
# ########
# Specials
# ########
# C+ => Cplus
# C++ => Cplusplus
"\u0043\u002B" => "Cplus"
"\u0063\u002B" => "Cplus"
"\u0043\u002B\u002B" => "Cplusplus"
"\u0063\u002B\u002B" => "Cplusplus"
# C#, C♯ => Csharp
"\u0043\u0023" => "Csharp"
"\u0063\u0023" => "Csharp"
"\u0043\u266f" => "Csharp"
"\u0063\u266f" => "Csharp"
# F#, F♯ => Fsharp
"\u0046\u0023" => "Fsharp"
"\u0066\u0023" => "Fsharp"
"\u0046\u266f" => "Fsharp"
"\u0066\u266f" => "Fsharp"
# J#, J♯ => Jsharp
"\u004A\u0023" => "Jsharp"
"\u006A\u0023" => "Jsharp"
"\u004A\u266f" => "Jsharp"
"\u006A\u266f" => "Jsharp"
# ♭ => b
"\u266d" => "b"
# @ => at
"\u0040" => "at"
*******************************
Then use any tokenizer

this is the field type i m using for techskill,
<field name="techskill" type="text_general" indexed="true"
stored="true" />
<fieldType name="text_general" class="solr.TextField"
positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt" enablePositionIncrements="true" />
<!-- in this example, we will only use synonyms at query time
<filter class="solr.SynonymFilterFactory"
synonyms="index_synonyms.txt" ignoreCase="true" expand="false"/>
-->
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>

主题： Re: Is there any special meaning for # symbol in solr.
if i use this link ,
http://localhost:8080/solr/select?&q=(techskill%3Ac%23)
, solr is going to display techskill:c result.
But i want to display only techskill:c# result.

error Like, org.apache.lucene.queryparser.classic.ParseException:
Cannot

Solr only received '(techskill:c', which has unbalanced parentheses.
My guess is that you do not perform a URL-encode of '#' and that you
were sending something like
http://localhost:8080/solr/select?&q=(techskill:c#)
when you should have been sending
http://localhost:8080/solr/select?&q=(techskill%3Ac%23)
