Search Engine ignores digits

Hi, for my internship, i've been asked to fix a search engine. It works, but there is one problem : it ignores digits. At first I thought it would be the anaylzer, but using Luke on the index files, we have seen that digits are indexed. We're using lucene 1.2, though I know it's not the latest version. I'm stuck really bad with this. Could anyone provide some help please ?
