Many people are accustomed to use simple keywords to search, for example, with "database" search for various industry databases, so certainly not, the results are too broad, most likely are some of the database software and design aspects of things, difficult to filter. In order to improve efficiency, need to carry out a precise search, can not use a single keyword search, we need to use a combination of keywords to search, such as "Industry Database", the industry is only a generic, we do the actual search, you can use specific industry words, such as "Cosmetics database". This can greatly improve the exact search scope.

Some database nature of information and sites, naming, not necessarily with the database naming, may use the directory, database, information base, statistical library and other words to name, so we can try to use these words with the industry words, keyword search, is also a good way of accurate search.

Start with URL features

Notice the space between the word and the word in the search expression.
