I wan't to search for certain numbers in my index but I'm having trouble with certain results. (I'm using edismax.)

Example:

    Term in index  I want to search: b1.123.456
    Query I use is b1 123 456 (no spaces)

This doesn't work because a . is not the same as a - (I've read the documentation) I looked for a solution and found that I have to use a Filter on my field:

<fieldType name="text_general" class="solr.TextField" positionIncrementGap="100">
  <analyzer type="index">
    <charFilter  class="solr.MappingCharFilterFactory" mapping="mapchar.txt" />
    <tokenizer class="solr.StandardTokenizerFactory"/>
    <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" />
    <filter class="solr.LowerCaseFilterFactory"/>
  </analyzer>
  <analyzer type="query">
    <charFilter  class="solr.MappingCharFilterFactory" mapping="mapchar.txt" />
    <tokenizer class="solr.StandardTokenizerFactory"/>
    <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" />
    <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
    <filter class="solr.LowerCaseFilterFactory"/>
  </analyzer>
</fieldType>

This is my fieldtype, the mapchar contains "."=>" "

Now when I try to search:

    b1.123.456   returns all results for each token (normal behaviour)
    "b1.123.456" returns what I'm looking for.
    "b1 123 456" returns what I'm looking for.
     b1 123 456  **returns nothing**

Why does a normal edismax query without phrase search return 0 results?

Edit:

I've found an error in the logs when I use the last query:

由于默认查询处理程序有效（/select），我开始认为我的查询处理程序有问题。

为了找出问题所在，我开始稍微禁用我自己的请求处理程序的一部分。 

  <!--<str name="mm"></str>-->

一个空的mm会给你错误！

我曾经有一个 mm 参数，但我真的不再需要它了，所以我把它留空了......
