Analyzer Tokenizer for Exact and Contains search on single field

[Satish Talim <sa...@gmail.com>]

I am a Solr newbie.

Let's say we have a field with 4 records as follows:

"James"
"James Edward"
"James Edward Gray"
"JamesEdward"

a. In Solr 3.4, I want an exact search on the given field for "James
Edward". Record 2 should be returned.

b. Next on the same field, I want to check whether "James" is contained in
the field, then records 1, 2 and 3 should be returned.

Which standard analyzer, tokenizer can one apply on one single field, to get
these results?

Hi Satish,

I don't think there is a single analyzer that does what you want.

However, you could send the info to a second field with copyField, and use e.g. WhitespaceTokenizer on one field for contains-style queries, and KeywordTokenizer on the other field (or just use the "string" field type) for exact matches.
