You may look for words, parts of a word or full expressions, throughout the title lists. This could give you a rough idea of your interest's occurence. The word "obturateur" is a good example of representativity as such. However, some words like "argent" will not lead to anything much since many titles do not mention it even though it certainly can be found in many patent texts. Furthermore, some titles will sometimes not tell anything at all about the patent's content, ie. "perfectionnements dans la photographie". Your only chance to aproach exhaustive research is to read every title (that can be done year by year), and consulting the contents of every "blind" title.
