  In this paper, we present the experimental work done on Query Expansion (QE)
for retrieval tasks of Gujarati text documents. In information retrieval, it is
very difficult to estimate the exact user need, query expansion adds terms to
the original query, which provides more information about the user need. There
are various approaches to query expansion. In our work, manual thesaurus based
query expansion was performed to evaluate the performance of widely used
information retrieval models for Gujarati text documents. Results show that
query expansion improves the recall of text documents.
