Goh<ref name=":2" /> and Chang and [[Michael Mitzenmacher|Mitzenmacher]]<ref name=":3" /> proposed security definitions for SSE. These were strengthened and extended by Curtmola, Garay, Kamara and Ostrovsky<ref name=":1" /> who proposed the notion of adaptive security for SSE. This work also was the first to observe leakage in SSE and to formally capture it as part of the security definition. Leakage was further formalized and generalized by Chase and [[Seny Kamara|Kamara]].<ref>{{Cite book|last1=Chase|first1=Melissa|last2=Kamara|first2=Seny|title=Advances in Cryptology - ASIACRYPT 2010 |chapter=Structured Encryption and Controlled Disclosure |date=2010|editor-last=Abe|editor-first=Masayuki|series=Lecture Notes in Computer Science|volume=6477 |language=en|___location=Berlin, Heidelberg|publisher=Springer|pages=577–594|doi=10.1007/978-3-642-17373-8_33|isbn=978-3-642-17373-8|doi-access=free}}</ref> Islam, Kuzu and Kantarcioglu described the first leakage attack.<ref>{{Cite journal|last1=Islam|first1=Mohammad|last2=Kuzu|first2=Mehmet|last3=Kantarcioglu|first3=Murat|title=Access Pattern disclosure on Searchable Encryption:Ramification, Attack and Mitigation|url=https://www.ndss-symposium.org/wp-content/uploads/2017/09/06_1.pdf|journal=Network and Distributed System Security (NDSS) Symposium}}</ref>

All the previously mentioned constructions support single keyword search.

The construction can also be extended to support disjunctive and Boolean searches that can be expressed in searchable normal form (SNF) in sub-linear time.
