On the other hand, what general search engine adopted is accurate matching algorithm, because the searching keyword of the information index of setting up in the system and user's input is not based on same standard, can cause information to omit problem; Have some synonyms as defined a lot of key word information in the full-text search of information, such as " marketing " and " sale ", " flow process " and " process ", " cooperation " and " cooperation " etc., if system does not take into full account the relevance of keyword when setting up index, the user is general direct input keyword when search, if the user does not grasp certain search skill when search, repeatedly do not attempt the synonym or the near synonym of searching keyword, then omit the information of falling to belong in the search intention probably, last result is gainless, when not only useless but also useless power.
_ also have the information search method of common a kind of tree directory structure, can only be confined to fixed sturcture and select along a certain branch, can not stride the multi-class comprehensive intersection of multiple-limb and select keyword, thus can not precise search, also have bulk redundancy information simultaneously.
Summary of the invention
Order of the present invention is to solve the problems referred to above that exist in existing information searching method and the system, proposes a kind of information search method and search system of default fixed keyword.
The technical solution used in the present invention is: the present invention proposes a kind of based on the fixed keyword information search method, system preestablishes the fixed keyword set, promptly each keyword in the set is the fixedly statement to a certain notion, and set by the system manager in advance, and when the user of system submits information and search information to, can only in this keyword set, choose keyword; When described system user submits information to, in the set of predefined fixed keyword, select any one or a plurality of keyword related with it; When thereby any system user searches for any information of above submission, can only be by in predefined fixed keyword set, selecting any one or a plurality of keyword search for.
Further, system classifies to the keyword in the set of described fixed keyword, so that information is submitted to and select during search.
Further, each keyword in the described fixed keyword is used to represent all close statement words of a certain same concept or same thought.
Further, add new fixed keyword in the described keyword set or revise keyword, can only be undertaken by the system manager is unified, described system user can not create, revise, delete any keyword.
Further, index set up in one or more keywords of selecting when submitted of described information.
The present invention also proposes a kind of information search system based on fixed keyword, described search system is stored in the information search system server, can user's searching request be responded, select the information that is complementary according to searching request from an indexed ensemble of communication, described user is meant and uses a computer or the user of computer network; Native system comprises: the predefined fixed keyword set record of system manager module, in predefined fixed keyword set, select the information of keyword to submit module to when information is submitted to, and in predefined fixed keyword set, select the information search module of keyword and the memory module of canned data set during information search.
Further, each keyword in the described keyword set is used to represent all close statement words of a certain same concept or same thought.
Further, add new fixed keyword or revise keyword in keyword set, can only be undertaken by the system manager is unified, described system user can not create, revise, delete any keyword.
In conjunction with the above, the keyword in the described keyword set is classified by system, so that information is submitted to and choose during search.
The invention has the beneficial effects as follows, overcome existing search engine method and can not in huge information ocean, accurately search the shortcoming of user's information needed, by when the information submission system, all relevant keywords of default are all related with it, when the user searches for according to the keyword of the default of selecting, coverage rate and accurate rate can reach absolutely, promptly can not miss the needed information of searchers, also can not find the unwanted information of searchers.
