You can ask NSA — I subscribed to the SEARCH service during the first week or so it was offered, and have done so since. If you keep any stats (please do...), I'd be surprised if anyone equals my number of searches. Generally I'm happy with the service. Like the built-in INDEX in windows, this search takes certain shortcuts (apostrophe (')- what is that?), liberties (quotation marks, question marks & Unicode characters (虎夢 is my name 'Hǔ mèng' in Chinese)) problematic, and for that matter the closing double parenthesis.
I often type in the name of a song, since I collect multiple covers of multiple songs. Tonight the SEARCH service crapped a sandpaper football.
I typed in "Its Now Or Never", without the quotes and missing the usually unrecognized apostrophe. The result did not contain one line in twenty with even the sub-phrase "Now Or Never", no quotes. It has seldom cared about capitalization. nsa is the same as NSA and so on.
What gives?? The SEARCH, in the last 48 hours, has taken a major turn for the useless. Try it. Then tell me what I did wrong. Nothing has changed in years, no sub-filters or specifications, searching the entire internet (as GigaNews sees it). What? Eh??
