The default search is "match any word", so a search on the full title turns up a huge volume of hits. Being posted yesterday the article was probably way down the list. I started to post the article this morning, but I searched on the exact title, as provided by the Houston Chronicle, and then searched again on a few keywords "mouse" and "fire" which turned up the article from yesterday.
It would probably benefit the forum if the search feature could prioritize by relevance.
