Although stop words are important, there is no provision (that I'm aware 
of) that can override them.

If "yes" or "no" are important words in your database, you're basically 
outta luck.

Suppose I wanted to find all  of the people in my database who were had 
drivers licenses and own vehicles.

I would include the following meta tags in their files:
<meta name="license" content="yes">
<meta name="ownscar" content="yes">

Of course, you can delete "yes" and "no" from swish.h, but they'll still 
show up as stop words because they appear in all or most of your files.

This is a function common to all database programs.

A variable like "Override_Stop_Words" in config.h or index.conf which would 
allow you to enter a few words like "yes" or "no"  would greatly enhance 
SWISH-E's usefulness.
