问题 I'm using the code listed here: http://msdn.microsoft.com/en-us/library/ms553069.aspx With an additional line added as a call to .update() after the property is set in order to save the changes, but even with a weight of 10,000 the search results for my property are still at the bottom, particularly below title. Is there some other things that need to be done in order to get the weighting to propogate? I've also tried setting the title, author, and filename to 0, setting the property

问题 Two Questions. When we declare literal strings, we search whether there is the same string in string pool of heap. Is this also an interning (method intern of class String )? In my thought, each literal string declaration needs a binary search or something so it costs at least log(n) when n is number of existing strings in the pool. And if there are many strings in the pool, it may be high cost. (maybe tradeoff of searching cost and memory?) On this point of view, it might be dangerous to

问题 I have a problem with a search with special characters in solr. My document has a field "title" and sometimes it can be like "Titanic - 1999" (it has the character "-"). When i try to search in solr with "-" i receive a 400 error. I've tried to escape the character, so I tried something like "-" and "\-". With that changes solr doesn't response me with an error, but it returns 0 results. How can i search in the solr admin with that special character(something like "-" or "'"??? Regards UPDATE

问题 When we have an array with indexes from 0 to n for example. when I use the Binary search using floor or ceiling when calculating the middle index I get the same out put. int middle = ceiling ((left+right)/2); Is there a reason using floor over ceiling ? what bug will happen using the ceiling ? 回答1: There's no difference in complexity. Both variants are log(n). Depending on the rest of your implementation, you may get a different result if your array looks for instance like 0 1 1 1 1 2 and

问题 I have a site that lists movies. Naturally people make spelling mistakes when searching for movies, and of course there is the fact that some movies have apostrophes, use letters to spell out numbers in the title, etc. How do I get my search script to overlook these errors? Probably need something that's a little more intelligent than WHERE mov_title LIKE '%keyword%' . It was suggested that I use a fulltext search engine, but all of those things look really complicated, and I feel that

问题 How can I search inside Blob column in MySQL for some values ? and Is that possible ? 回答1: You should be able to search blobs like other text fields: SELECT * FROM tablename WHERE blob_field_name LIKE '%value%' One thing to notice is that search will be case-sensitive! Anyway, if possible, it's better to use a TEXT field. 回答2: If you want to make it work for both uppercase, lowercase or mixed... Make the search string in lower case before applying in mysql query and use LOWER() mysql function

问题 I've got a page with a bunch of thumbnails and titles: http://thenozzle.net/games (broken link) If you hit "search", a search bar slides down from above. I can type things into the search box and hit enter to search the website. I was wondering if there was any way to look at all the thumbnails, and if I typed "E" it would hide all the thumbnails except for ones that started with "E". Then I typed "El" and it brought up every result that started with "El". Then I added a "d" and it would

问题 The below code now works but how can I make it so if no results are found it echos a message instead of blank. I think I've managed to create a search query for my database. Its only a very basic search but it doesn't seem to work for some reason. Any advice would be appreciated im still new to pdo (very new! be kind!). Also no user submitted data is inserted into the database so I think i can rule out xss assuming its SQL inject free? Which from what I understand PDO is? plus im using a
