use wildcard in solr facet query search

Question

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:

ValX ValY
ValX
ValZ ValW
ValX ValV
ValA ValX
ValA ValB

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.

Answer 1

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.

Answer 2

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.
