search

问题 I have a big sql file that contains a lot of 'create table ...' and 'insert ...' queries. Now I want to eliminate all the 'insert' queries from the file. The insert queries are somewhat like: INSERT INTO 'some_table' (col1, col2, col3) values ('val11','val12','val13'), ('val21','val22','val23'), ('val31','val32','val33'); Using Notepad++ I want to find and delete all these 'INSERT' queries using regular expression. When I tried finding with the regex INSERT INTO((.*\r\n)*) then it selects

It works great except that when I insert a space character in editbox it somehow doesn't recognize it and the result set comes empty.

问题 I try to create a regular expression with searches in a huge document for a persons full name. In the text the name can be written in full, or the first names can be either abbreviated to a single letter or a letter followed by a dot or omitted. For instance my search for _ALBERTO JORGE ALONSO CALEFACCION_now is: preg_match('/([;:.,&\s\xc2\-(){}!"'<>]{1})(ALBERTO|A.|A)[\s\xc2-]+ (JORGE|J.|J)?[\s\xc2,]+(ALONSO)[\s\xc2*-]+(CALEFACCION))([;:.,&\s\xc2(){} !"'<>]{1})/i', $text, $match); Between

问题 My search is not working now. I guess because my index was not configured for replica set: curl -XPUT 'http://localhost:9200/_river/mongodb/_meta' -d '{ "type": "mongodb", "mongodb": { "db": "mongo", "host": "local", "port": "40000", "collection": "users" }, "index": { "name": "api", "type": "users" } }'` Is there anyway to declare a replica set properly so that elasticsearch can find the master, the way PHP driver does: $m = new Mongo( "mongodb://localhost:40000,localhost:41000", array(

问题 I'm developing an android application for a store, which provides many functions. One of these is a function that allows the customer to search a product with some criteria (price,size,type... like in the picture ). I guess I should work with SqliteDatabase , but I have no idea how I can make this multi-criteria search interface , so the user can query the database. 回答1: It's simple. after setup your database, you can use SQL queries and JOIN types with WHERE critaria and finally achive

问题 I have a piece of code that works in the following way. There is a matrix of size n x 2 . Each element is an integer between 1 and some maximum, say m . I want to search for rows in this matrix, that is, given [v1, v2] , output the index of this. Right now, I am using: k = find(ismember(edges, [v1, v2], 'rows')); However, this is the bottleneck in my code because this is in linear time. I would like to implement some hashmap type structure for fast lookup. What would be an easy way to do this

问题 I am currently experimenting using the ransack gem to conduct a search on a model in Rails. As it stands I am using the basic setup. Controller: def index @q = Person.search(params[:q]) @people = @q.result(:distinct => true) end View: <%= search_form_for @q do |f| %> <%= f.label :name_cont %> <%= f.text_field :name_cont %> <%= f.submit %> <% end %> I have managed to find lot of information about conducting searches on multiple fields, however, I haven't managed to find anything to help me to

问题 Following Solr documentations (https://cwiki.apache.org/confluence/display/solr/Function+Queries and others) I should just put idf(fieldname, 'term') as I do with termfreq(fieldname, 'term') in the field list. However, whenever I try this I get an exception as: org.apache.solr.client.solrj.SolrServerException: No live SolrServers available to handle this request By looking at the logs I could find: null:java.lang.UnsupportedOperationException: requires a TFIDFSimilarity (such as
