Think about which parts of the acronym listings you want to search in. By default, the 'Acronyms' and 'Expansions' checkboxes are checked. If you're after acronyms which have to do with a particular topic, this is usually the best setting, however read the notes below for some exceptions. If you want to find an expansion of a particular word, just search in Acronyms, as that will look for an actual acronym containing that word, which will of course have an expansion. If you want to find acronyms by a particular person, type in that person's name and search only in the credits.
Some credits have explanations of the acronyms which can be useful to search in.
Not all Pokemon names mention the word 'Pokemon' in the expansions, so in this case only searching in the acronyms and expansions wouldn't work very well. Similarly, if you're looking for expansions of Shakespeare characters, search for Shakespeare or for the name of the particular play in the credits. You can continue searching within the results of previous searches as much as you like, so you can get really specific results. If you're looking for an explanation of an acronym which is in common use, you should probably try searching Acronym Finder . They have 'real' acronyms, we have made up ones.
