问题 I have two Solr cores. Core0 imports data from a Oracle table called items. Each item has a unique id (item_id) and is either a video item or a audio item (item_type). Other fields contain searchable texts (description, comments etc) Core1 imports data from two tables (from a different database) called video_item_dates and audio_item_dates which record occurrence dates of an item in a specific market. The fields are item_id, item_market and dates. A single row would look like (item_001,

问题 How do I perform a binary search on a single linked list headed ? Also it can do it , if there is any particular method. The EP can not tell in advance how many elements of that list , I have to search and enter a cell between q > prox and p . 回答1: Typically this is not possible, since binary search requires random access, and a singly-linked list can only provide forward sequential access. Without being able to jump around in memory and look at some nth element (either through direct random

问题 How do I tell query_string which analyzer to use in a search? I've created my index with an analyzer like so: "analysis": { "analyzer": { "std_analyzer": { "tokenizer": "whitespace", "filter": [ "stemmer" ] } } } I do not predefine any mappings. Instead, I rely mappings to be dynamically added upon inserting a document. The mappings appear like so after calling /my_index/_mapping "short_bio" : { "type" : "text", "fields" : { "keyword" : { "type" : "keyword", "ignore_above" : 256 } } }, You

问题 One can search the full tic tac toe game tree, using only fail fast optimization of negation as failure, in less that 100ms. Thats what this solution does using a holistic representation of the game state as a single Prolog term: ?- time((init(X), best(X, x, _))). % 92,055 inferences, 0.031 CPU in 0.031 seconds (99% CPU, 2984342 Lips) false. The above solution uses a single term for the board, here is an example from the code: init([[-, -, -], [-, -, -], [-, -, -]]). Are there any Prolog

问题 I'm trying to create a program where I can search for some files in a directory on my PC, using Visual Studio C++. As I'm not very experienced with that, I found this code (below) in another answer but couldn't find any explanation to the code. I'm having a hard time figuring it out and would strongly appreciate any help possible. If there's another way of doing this I would be pleased to know how. Thank you! " Now you can get file names. Just compare a file name. while ((dirp = readdir(dp))

问题 I am trying to filter a table based on data attribute, instead on value inside the td tag. The problem is, that I can't get it to work, because I always get this error: Uncaught TypeError: Cannot call method 'match' of undefined $(document).ready(function(){ var elemens = $("td") searchInput = $("#search") searchInput.on('keyup',function(){ elemens.each(function(){ var re = new RegExp(searchInput.val(), 'gi'); if( $(this).data('gui').match(re) === null ) { $(this).parent('tr').hide(); }else{

问题 Useful information: For information on how to sort a list of various data types see: How to sort (list/tuple) of lists/tuples? .. and for information on how to perform a binary search on a sorted list see: Binary search (bisection) in Python My question: How can you neatly apply binary search (or another log(n) search algorithm) to a list of some data type, where the key is a inner-component of the data type itself? To keep the question simple we can use a list of tuples as an example: x = [(

问题 I have a synonyms.txt file with content as below car accessories, gadi marmat and I am indexing car accessories as a single token so that it will expand to car accessories and gadi marmat . i want the whole synonyms to match so that when query for gadi marmat , the record with car accessories to be returned.
