If you can post back with the product results page I can show you where to make this edit.
As for the search what should the result be of the search term you posted? I can see that there are hundreds of results when I use that search string.
As a simple test of the search I used the word snail and got back 3 products with the word snail in them. I then searched for moses and got 4 results. If I search for moses snail I get back six results (one of the items fits both searches). So the search is using an or comparison as the space separator. Would you like it to use 'AND' for this rather than 'OR' and ensure that all of the terms entered match?
