wildcard search for string having spaces

Hello,

I have below custom field type defined for solr 6.0.0

   <fieldType name="my_string" class="solr.TextField" positionIncrementGap="100" multiValued="true">
    <analyzer type="index">
      <tokenizer class="solr.KeywordTokenizerFactory"/>
      <filter class="solr.LowerCaseFilterFactory"/>
    </analyzer>
    <analyzer type="query">
      <tokenizer class="solr.KeywordTokenizerFactory"/>
      <filter class="solr.LowerCaseFilterFactory"/>
    </analyzer>
  </fieldType>


I am using above field to ensure that entire string is considered as single token and search should be case insensitive.

It works for most of the scnearios with wildcard search.
e.g. if my data is "abc.pqr" and "abc_pqr" and "abc pqr" then search with abc* gives this three results.

But I am not able to search with say abc p*

Search with query q="abc pqr" gives exact match and desired result.

I want to do wildcard search where criteria can include spaces like above example


i.e. if space is present then I am not able to to wildcard search.

Is there any way by which wildcard search will be achieved even if space is present in token.

Regards,
Roshan

Great.
First option worked for me. I was trying with q=abc\sp*... it should be q=abc\ p*

Thanks

Hi Roshan,

I think there are two options:

1) escape the space q=abc\ p*
2) use prefix query parser q={!prefix f=my_string}abc p
