The "OR" boolean and match method do exactly this.

This seems to be a different question. It *does* perform OR by summing
weights, I'll show you the code if you wish. However it seems like you're
saying that changing the order of a query changes the weight of the word.
This doesn't happen either. Just to be sure, I took several multi-word
queries and took a "diff" to see what changed if I changed the order. They
were identical, except the header at the top. :-)
The only time words in a query are given different weight is if fuzzy
matching is used. In that case, they're given the weights in the
Remember also that documents may be heavily weighted in one word or
another. For example, some words are excluded in the bad_words list, others
are given more importance based on markup, some are more common than
