问题 Let me explain my problem. I am using Lucene to search and display the results in asp.net web page. When I am searching, the Lucene is displaying all the records associated with my search. For Example I have 5000 records with name John. If I type John it is displaying all this 5000 records. I want to restrict this 5000 records based on some other attribute. I have four attributes namely First Name, Last Name, DOB and ID. Out those 5000 records I want it to display only the ones with the

问题 I have a problem. I made a simple search engine which searches by brand and model of car. For reasons of query performance and a lot of data in database, I decided to use full-text search. It's ok, but now I come across the problem: I would like to find all cars with brand "Audi" and with model "Q7". For now, I have this SQL query, but it doesn't work right, because of word length "Q7": SELECT `a`.`id`, `a`.`title`, `a`.`askprice`, `a`.`description`, `a`.`picture` FROM (`mm_ads` as a) WHERE

问题 I noticed that quite a lot Dropbox pages are indexed by Google, Bing, etc. and was wondering how these search engines obtain for instance links like these: https://dl.dropboxusercontent.com/s/85cdji4d5pl5qym/37-71.pdf https://dl.dropboxusercontent.com/u/11421929/larin2014.pdf Given that there are no links on dl.dropboxusercontent.com to follow and the path structure is not that easy to guess, how is it possible that a search engine obtains such a link? One solution might be that it was posted

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . I know that this question has been asked many times ( but in different varuations), but I got totally confused... I have a website with a right panel displaying some content - a set of links to news/inner articles. This is the same list for all site's pages. Thus, every time there is a new link/line in th news

问题 I have a location search website for a city, we started out with collecting data for all possible categories in the city like Schools, Colleges, Departmental Stores etc and stored their information in a separate table, as each entry had different details apart from their name, address and phone number.
