Abstract
A method for managing a document search index. The method includes obtaining indexing terms for documents in a document repository to generate search index fragments, storing the search index fragments in a document search index, and constructing a hierarchical structure from a first set of stored search index fragments. The selected first set of search index fragments is arranged by size, in the hierarchical structure. The method further includes selecting, based on a minimal size, a second set of stored search index fragments from the hierarchical structure, merging the second set of stored search index fragments to obtain a larger search index fragment, storing the larger search index fragment in the document search index, and serving at least one search request using the larger search index fragment.
