You could look at using your own custom operator. <div><br></div><div>Wolfgang Laun linked to an article of his recently explaining the approach.<div><br></div><div>I'm not sure if custom operators however allow for indexing in the RETE network and therefore whether they're any faster than eval.</div>

We have a requirement to display data as stored (with the right casing) but<br>
for evaluation purposes strings should be compared case in-sensitive. We<br>
have several hundred rules touching these particular strings and would<br>
really like to avoid doing eval( x != null && x.equalsIngoreCase(y) )<br>
everywhere. Is there anywhere in drools that we could configure to make<br>
string matching case in-sensitive?<br>
<br>
Since we have to display the data with casing elsewhere, putting<br>
x.toLowerCase() in all our getter methods doesn't seem to be an option.<br>
