SQL error when search keyword is too small

I don't get the same error. Please make sure that you have views_fastsearch.module 1.2.2.13 that has the following check on line 140:

      // if there aren't any words
      if ($word_count == 0) {
        $query->add_where($filter['operator'] == 'AND+' ? '1' : '0');
        return;
      }

I am getting the error with a later version of the views_fastsearch.module (1.2.2.18).

The check above does appear on line 162, however, searching for a small keyword gives me the following error:

warning: array_fill() [function.array-fill]: Number of elements must be positive in <snip>/sites/all/modules/views_fastsearch/views_fastsearch.module on line 272.

Please ignore my last comment. It appears I am getting this error for *all* searches besides small keywords :)

I'll continue researching and open an issue if I find something.

Thanks! I just released this version yesterday. It uses some new logic for even faster searches. Please read the release notes. The error you are getting is in the old method of doing queries, that I still need to debug.

The latest build should fix the php error. I still need to do some debugging to make sure that it's generating the right queries.

btw, I think that the small words are being excluded properly. I just tested with both the old search and the UNIQUE search, and both seem to work.

my bad for not reading the release notes before trying the version.. thanks for noting that..
