How to search for a word in facet query in solr (or in other words how to use wildcard in search by facet)
for example if i have facet filed MyField and it has the following values:

  1. ValX ValY
    2. 

  2. ValX
    3. 

  3. ValZ ValW
    4. 

  4. ValX ValV
    5. 

  5. ValA ValX
    6. 

  6. ValA ValB
    7.

now if i search for fq=MyField:ValX, i will get the second record only. how can i search for ValX and get the 1st, 2nd, 4th and 5th records?
you know fq=MyField:*ValX* is not allowed and fq=MyField:ValX* will not return the 5th record.
any idea is highly appreciated.

Is this not supported by SOLR fq=MyField:*ValX*? If so how it can be achieved ? i want to filter based on a matching text like *text*. Thanks – Pranay

How is MyField defined in schema.xml? Looks to me as if it isn't tokenized, like for instance with

type="string"

With

type="text"

the field value is tokenized so that 

fq=MyField:valx

should match 1, 2, 4 and 5.

Wildcard card on Facet Query should work.

As wildcard queries does not undergo any analysis, you can try fq=MyField:valx*

What you are trying is not filtering but rather searching.
Use a white space tokenizer with lower case filters and search q=MyField:valx and it would match the results. You can use prefix and wildcard queries with it as well.
