Initially, with a subscription model for people with an interest in search results relevant to their purpose rather than suffering through search results relevant to the purposes of advertising sales. This will allow controlled growth to match resources to volume.
[edit] The right model might be a sort of meta-search engine - feed the regex to something like Wikipedia to determine plausible keywords and then return aggregated search results based on the keywords. At prototype and small scale actual search results could be aggregatte from other search engines such as Google or Bing.
[edit] Interestingly, Wikipedia already has regex capability built in to AutoWikibrowser.

- how will you implement this cheaply enough?
- who will really use this? what are they doing now instead?
