Hi,

Here's what i get when i search with "AND" or "OR" terms:

The query itself, for instance "name:AND~0.4"

Response from couchdb-lucene:

{"reason": "Bad query syntax: Cannot parse 'name:AND~0.4': Encountered \" \"AND \"\" at line 1, column 41.
Was expecting one of:
\"(\" ...
\"*\" ...
<QUOTED> ...
<TERM> ...
<PREFIXTERM> ...
<WILDTERM> ...
\"[\" ...
\"{\" ...
<NUMBER> ...
",

"code": 400}

Is it a bug or specifics of underlying Lucene processing? If it's Lucene specific, then what would be the best way to handle this problem?

AND and OR are part of the query syntax. try name:"AND" and name:"OR" instead, though bear in mind that both words are part of the standard analyzer's stop word list and are not indexed (as they are generally regarded as poor search terms).

I did. But then it wouldn't work with fuzzy operator....

I am searching on company names. So I must treat OR and AND as part of name (e.g. company name is transliterated from a foreign name... so you could have smth like "Or & Ar Co. Ltd." ).

I applied a per-field simple analyzer on a company name and it seems to be OK for now. Hope that was a right choice :)
