TYPE-AHEAD SEARCH OPTIMIZATION

Techniques are provided for efficiently performing a series of searches. After an initial set of search results is determined from a data set based on a search query, one or more additional characters are added to the search query. In response, another search is performed, using the updated search query, but the new search is limited to searching the initial set of search results. Thus, the original data set is not accessed or searched again. This is possible due to the nature of the data. Each subsequent search is based on one or more characters that were added to a previous search query. Thus, each subsequent search is constrained to the search results that were identified in a previous search.
