Abstract
The technology described herein provides for indexing information in a bit vector search index. 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. The bit vector search index is stored by first indexing information about documents using bit vectors on a first accumulation buffer storage device. When a threshold is satisfied, the information is transferred to bit vectors on a subsequent storage device.
