search

问题 I have a Stored Proc which performs search on records. The problem is that some of the search criteria,which are coming from UI, may be empty string. So, when the criteria not specified, the LIKE statement becomes redundant. How can I effectively perform that search or Sql Server? Or, Does it optimize LIKE('%%') query since it means there is nothing to compare? The Stored proc is like this: ALTER PROC [FRA].[MCC_SEARCH] @MCC_Code varchar(4), @MCC_Desc nvarchar(50), @Detail nvarchar(50) AS

问题 I'm using the imap_search to get a list of messages from my INBOX. I want only the emails sent from the address, lets say "somemail@gmail.com". I'm doing like: $headers = imap_search($box,'FROM "somemail@gmail.com"', SE_UID); But this takes so many time, around 3 minutes and the inbox have only 700 emails (my box is GMAIL). The problem is not from the server, because i installed roundcube in the localhost and loads the emails quickly. What can i do to make it faster? 回答1: This method has

问题 Hi everybody If someone search for term "zali se mami" in mySql database, what is the best way to make all possible replacements with appropriate signs (for example e => ë, e => é, a => ã, u => ü, u => ú...) so he/she could get all possible results like: "žali se mami" "žali se màmi" "žàli se mami" "žàli së mami" Thank you in advance for your help 回答1: Use the utf8_general_ci collation on the column. You can read more about the effects of the collation at these two pages in the MySQL manual:

What I am trying to create is basically a table of indexes separated by spaces (or whatever type you fancy). I realize that Full Text Search would not be possible on merely int

问题 So I'm working on a search function for a social networking site, and it searches user posts. Some users like to put hyphens instead of spaces, but I would like for the search function look for both hyphens and spaces in a result. For example, if they have a post named "SQL-IS AWESOME" and I search for "SQL IS AWESOME", can I still find that post? I tried using 2 sql queries, one for the original search query, and one modified to change all spaces to hyphens. But if I search "SQL IS-AWESOME"

问题 This is a homework exercise from Steven Skiena's "The algorithm design manual" 2nd edition, p 143. Suppose that you are given a sorted sequence of distinct integers {A1,A2,...An} , drawn from 1 to m where n < m . Give an O(lgN) algorithm to find an integer <= m that is not present in A . For full credit, find the smallest such integer. A sorted sequence, and O(lgN) both suggest a binary search algorithm. The only way I could think of is to run through numbers from 1 through m , and for each

问题 All the literature and implementations I've found of Aho-Corasick are about building the entire trie beforehand from a set of phrases. However, I'm interested in ways to work with it as a mutable data structure, where it can handle occasional adds and removes without needing to rebuild the whole trie (imagine there are 1 million entries in it). It's OK if the worst case is awful, as long as the average case is close to logarithmic. From how I figure it, the fail state for each node is another

问题 I am implementing a solution in Solr where I have a lot of values in my facet. As opposed to displaying a long list of values(facets) down the side of my page I want to display the top 10. And also have one for other. For instance I would be faceting on Nationality. So, I do not want to have a list of every nationality, Nor do I want a "see all" button. What I require is the top 10 nationalitys and then "Other". When a user clicks on other, it facets on this? 回答1: This is quite easy in Solr..
