Error searching for

FT.CREATE User SCHEMA name TEXT
FT.ADD User 'bob'
FT.SEARCH User ''

RESULT
(error) Syntax error at offset 0 near ''

Sometimes UI searches pass empty strings when person clicks Search w/o specifying anthing

It's still an error... you should catch that exception in your client, or not pass it to the server at all

I mean, I might change it, but it's a matter of taste basically.

I am catching it in my library https://github.com/dmitrypol/redi_search_rails but thought you might want to know

[dvirsky]

I know, but I hate to put something like:

if (strlen(query) == 0) {
// ignore the syntax error in the parser
}

so now what if the query is " "? or "   "? or ",. ?---- !!!? " or "a" (which is a stopword) - all of those are empty queries, I don't want to pre-process the query. I want the parser to just get it and do its best to parse it.

let's try this - I've added a rule in the grammar for empty queries. pull master and try it.
