search

问题 I was trying to search for a particular word in a matrix of characters through C but was unable to come to a fixed solution. For ex: Suppose I have to search for the word INTELLIGENT in a matrix of characters (3*9) (Once you have picked a character from the matrix to form a sentence, you cannot pick it again to form the same sentence.There is a path from any cell to all its neighboring cells. A neighbor may share an edge or a corner.) IIIINN.LI ....TTEGL .....NELI Output: YES (the word

问题 I have implement search for my application. For that I have used an adapter as well. I have loaded 30 items to the search screen. When I pressed letter z to search, then letter z belongs to 4 items out of 30 items in the list. According to the below shown code it identifies the number 4 and shows the first 4 items out of the 30 items. When I debug inside getFilter() , it shows the filtered items correctly(I have provided a screen shot). My problem is how can I load the filtered items. Bit

问题 I've got an ElasticSearch index with a large set of product properties.

The details of the exception are as

问题 I have a directory of about 30,000 text files and I'd like to search inside each to find if they contain a specified text. How can I do this effectively in PHP? 回答1: grep is your friend. You can use one of php's functions that allow execution of external commands to call it, if for some reason you need the result inside a PHP script. 回答2: 1) Use grep as mentioned above 2) Cache the search results so you don't have to search 30,000 text files for the same search term again. 回答3: As the others

问题 What could be a good way to code a search functionality for searching documents in a java web application? Is 'tagged search' a good fit for such kind of search functionality? 回答1: Why re-invent the wheel? Check out Apache Lucene. Also, search Stack Overflow for "full text search" and you'll find a lot of other very similar questions. Here's another one, for example: How do I implement Search Functionality in a website? 回答2: You could use Solr which sits on top of Lucene, and is a real web

问题 I have a number of functions that create search strings @/ I would like to know from which functions comes the search string. Is it possible to add an indicator to the search string that doesn't influence the search string but what allows me to check from which function it comes? p.e. /[indicator]search string 回答1: You can add a regexp branch that never matches, e.g. /\%$indicator\|search string \%$ is a special Vim atom matching the end of the file. Since that will never match when followed

问题 I have a list of strings to search along with a list of words and want to produce boolean feature vectors indicating presence of each word within the strings. What is the fastest way to build these feature vectors in Python? In the example below the first string would output [1, 0, 1, 1] for example. I'm currently using the Aho Corasick algorithm (Python - find occurrences of list of strings within string) to search each string in a list comprehension but think it's possible there's a faster
