Abstract

Subject matter described herein includes a multi-layer search-engine index. Accordingly, the search-engine index is divided into multiple indexes, each of which includes a respective set of information used to serve (i.e., respond to) a query. One index includes a term index, which organizes a set of terms that are found among a collection of documents. Another index includes a document index, which organizes a set of documents that are searchable. A computing device is used to serve the search-engine index (i.e., to analyze the index when identifying documents relevant to a search query). For example, a solid-state device might be used to serve the multi-layer search-engine index.
