  The Use of genetic algorithms in the Information retrieval (IR) area,
especially in optimizing a user query in Arabic data collections is presented
in this paper. Very little research has been carried out on Arabic text
collections. Boolean model have been used in this research. To optimize the
query using GA we used different fitness functions, different mutation
strategies to find which is the best strategy and fitness function that can be
used with Boolean model when the data collection is the Arabic language. Our
results show that the best GA strategy for the Boolean model is the GA (M2,
Precision) method.
