Subject Re: exact field match
Date Mon, 26 Jan 2009 22:08:39 GMT
Another solution is to put a special token in front and end of every  
occurence of the field, eg aastartaa in front an zzendzz in the end (a  
solution looking like Fasts boundary match feature behind the hood),  
You could then search for exact match ("aastartaa your phrase  
zzendzz"), and you would also get support for 'begins  
with' ("aastartaa your phrase"), 'ends with' ("your phrase zzendzz")  
and, if you need it, boosting of short field values ("aastartaa your  
phrase zzendzz"~10000) - a feature several others have been asking for  
earlier on on this list.
