Anhui Tejiu Group is a leading enterprise in the high-grade wine industry in China, and vodka is its flagship product. From 65438 to 0998, the group tried to search the market information of vodka through the Internet to open the European and American markets. To this end, the group set three objectives for information collection: price information, tariffs, trade policy and international trade data, and trade object information. Because the target is clear, it has received good retrieval effect.
When the depth of retrieval is related to the pertinence of requirements. If the demand is targeted (such as vodka) and involves a large number of specific fields and professional vocabulary, it is necessary to conduct in-depth search. The breadth of retrieval refers to the aspects and fields involved in information. The retrieval of supply and demand information in the general market does not need to be too deep, but it should have higher requirements in the breadth of information.
When the retrieval concept is relatively general, and a clear retrieval concept has not yet been formed, or when you only need to browse a certain topic extensively, you can use the appropriate categories of the topic guide to browse step by step until you find relevant websites and keywords before expanding your search. Fuzzy query is also called intelligent query. When a keyword is input, the search engine will not only feed back the website containing the keyword, but also send the content with similar meaning to the keyword. For example, if you look up the word "network economy" on the website, the fuzzy query will feed back the websites containing "network economy papers", "network economy and social development" and "information economy". The order of the websites that are fed back is generally: the information that completely meets the keywords is at the front, and the similar information is at the back. General search engines have this function, but the fuzzy programs are different. There is no special method for fuzzy query, just enter keywords in the text box.
