Operators Not Needed? the Impact of Query Structure on Web Searching Results
نویسنده
چکیده
Most Web searchers use extremely simple queries. There is an assumption that the correct use of query operators will improve the quality of results. We test his assumption by examining the impact of query operators on the documents retrieved from Web searching. We compare the results from queries without operators to results from the same queries using a variety of operators on several major web search engines. There were 1900 queries submitted, which returned 18,332 documents. In general, there was an average 66% similarity between results from the queries with and without operators. Implications on the effectiveness of current searching techniques, for future search engine design and of future research are discussed.

متن کاملRelational Databases Query Optimization using Hybrid Evolutionary Algorithm
Optimizing the database queries is one of hard research problems. Exhaustive search techniques like dynamic programming is suitable for queries with a few relations, but by increasing the number of relations in query, much use of memory and processing is needed, and the use of these methods is not suitable, so we have to use random and evolutionary methods. The use of evolutionary methods, beca...
