Zusammenfassung:The technology described herein provides a bit vector search index for a search system. The bit vector search index comprises a data structure for indexing data about terms from a corpus of documents. The data structure includes a number of bit vectors. Each bit vector comprises an array of bits and corresponds to a different set of terms. Bits in the bit vector are used to represent whether at least one document corresponding to the bit includes at least one term from the set of terms corresponding to the bit vector.
