search

问题 I have indexed the data from solr.xml and monitor.xml that came with the solr package, and I added the below configuration in the schema.xml file <field name="my_field" type="my_field_type" indexed="true" stored="true" required="false"/> <copyField source="name" dest="my_field" /> <fieldType name="my_field_type" class="solr.TextField"> <analyzer type="index"> <tokenizer class="solr.KeywordTokenizerFactory"/> <filter class="solr.PatternReplaceFilterFactory" pattern=".*" replacement=

问题 I've tried malloc , and no malloc and it will build but not run or compile. When I run the code on codepad.org it gives me a segmentation error. I have an array of structures I'm inputting and I'm searching through them for a specific item. That's as far as I got and no compile. The code is as follows (I used netbeans, codeblocks, and visual basic 2012 programs): #include <stdio.h> #include <stdlib.h> #include <string.h> #define SIZE 20 #define BLOODTYPESIZE 4 #define MAX 120000 typedef

问题 I've read through a few stackoverflows on this topic, as well as the wikipedia on A* but I'm still a little confused. I think this post almost explained it completely to me: A* heuristic, overestimation/underestimation? My only confusion left is, how does the A* know the optimal solution? It seems like with an admissible heuristic, you can throw out paths that exceed the known optimal solution, because the heuristic is guaranteed to be less than or equal. But how would A* know the optimal

问题 i have this data in my index https://gist.github.com/bitgandtter/6794d9b48ae914a3ac7c If you notice in the mapping im using the ngram from 3 tokens to 20. when i execute this query: GET /my_index/user/_search?search_type=dfs_query_then_fetch { "query": { "filtered": { "query":{ "multi_match":{ "query": "F", "fields": ["username","firstname","middlename","lastname"], "analyzer": "custom_search_analyzer" } } } } } I should get the 8 documents i have indexed but i get only 6 leaving out two with

问题 Im trying to put checkmarks after doing a search. I've seen some answers here but it doesn't work for me. Ive tried some of the answers but it will only make an error. Here's the code that I wrote. struct finalCheckednames { var name: String; var checkMark: Bool} class ShowBroadcastNamesViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, UISearchBarDelegate { var nameslist = ["Mark","Chris", "James", "Sandra"] var myIndex = 0 var nameArray = String() var filteredData

问题 I have a Model within Laravel called Blah (I named it this way because you can't simply name a class Class , so I changed the name temporarily).

问题 I'm creating a sidebarsearch(by clicking options), and picking the variables clicked to create sql query. More specifically: 1. user selects options in sidebar. 2. I create str(as url to be called) based on those selections adding params as 'param1=value&'... 3. ajax call to php controller->model->query dababase based on params via $_GET. I use the prepared statements in the end but in theory the attacker can make up their own url. To avoid this i pre specify the allowed values($keysArr) and
