 4. **Boolean Model**, you can set which field to search and the boolean model for each query token, such as "OR", "AND".
 5. **Combined Boolean Model, TF/IDF Model and the Vector Space Model**, makes the results ranking more reliable.
 6. **Fast**, Elasticlunr.js removed TokenCorpus and Vector from lunr.js, by using combined model there is **no** need to compute the vector of a document and query string to compute similarity of query and matched document, this improves the search speed significantly.
-7. **Small Index Size**, Elasticlunr.js did not store TokenCorpus because there is no need to compute query vector and document vector, then the index file is small, and also user can choose if they need to store the origianl JSON doc, if user cares more about the index size, they can choose not store the original JSON doc. This can reduce the index size significantly. This is especially helpful when elasticlunr.js is used as offline search. The index size is about half size of lunr.js index file.

 Sometimes user want to expand a query token to increase **RECALL**, then user could set expand model to **true** by configuration, default is **false**.
