Writing "OR -" is simply the same as "-", so the query would match documents
containing category 20 and then remove all documents that had any category
(including 20) specified, giving you nothing.
Try:
http://localhost:8983/search?q=*:*&wt=json&start=0&fq=category:"20"; OR
(*:* -category:[* TO *])
Technically, the following should work, but there have been bugs with pure
negative queries and sub-queries, so it may or may not work:
http://localhost:8983/search?q=*:*&wt=json&start=0&fq=category:"20"; OR
(-category:[* TO *])

I got an answer.
i can use http://localhost:8983/search?q=*:*&fq=-category:[* TO *]
but now i am facing a problem. that i want to search all docs .. who does
not have category field or category field value = 20
I wrote following query.
http://localhost:8983/search?q=*:*&wt=json&start=0&fq=category:"20"; OR
-category:[* TO *]
but it is giving me zero output.
http://localhost:8983/search?q=*:*&wt=json&start=0&fq=category:"20"; ->
output = 2689
