How can I choose the best search engine with an open source code?

Open source search engine selection for a web can be difficult, partly because - from outside - all of them show relevant search results based on a search term, so they all seem similar. Having an additional index that can dynamically index new statements, prevents administrators from regenerating the entire index. Stop Words, especially for large websites, are powerful open -source search engine tools because they allow users to reduce results. Fuzzy search features means that the search engine is able to find similar results based on the keyword, although the results do not exactly match the key word. The evaluation systems determine how each listing is displayed and should reflect how the main site works. Although this list is usually long, it will usually be extended when using the site. When the Grow Index must normally regenerate the entire index and add all new websites and statements; It takes time and a lot of resources. With the natureThe new statements are added dynamically and there is no reason to regenerate the entire index; The administrator must only add new information.

If someone enters a search term in a search engine with an open source code, it gets relevant results. This is not always the case and the results may tend to be irrelevant. For example, if a user is looking for pirates, he can only find a website about pirate films and not historical information about the Pirates. Stop Word allows the user to place the "-" brand before a word calling search engines to block the results that include this keyword.

Fuzzy search features sounds wrong, but it's a useful tool that employ many search with open source codemine programs. Without this, the search engine can only search for websites and statements that directly reflect the keyword. Fuzzy search brings results similar to key SLOvu so the user receives wider results.

Open source search engine rating system is the way the search engine determines relevance. Some Basic Relevance search engines to the number, how many times a keyword has been used when a listing or web has been created, the number of links pointing to one site or any other of any value. The administrator should choose a search engine that reflects how the site itself works. For example, if the main site allows users to publish lists, the date -based search module usually works best.
