Abstract
Methods, systems, and apparatus, including computer program products, for segmenting text for searching are disclosed. In one implementation, a method is provided. The method includes receiving text; segmenting the text into one or more unigrams; filtering the one or more unigrams to identify one or more core unigrams; and generating a searchable resource, including: for each of the one or more core unigrams: identifying a stem, indexing the stem, and associating one or more second n-grams with the indexed stem. Each of the one or more second n-grams is derived from the text and includes a core unigram that is related to the indexed stem.
