Elasticsearch aggregate on URL hostname

由 让人想犯罪 __ 提交于 2019-12-06 05:48:56
问题 I am indexing documents with a field containing a url: [ 'myUrlField' => 'http://google.com/foo/bar' ] Now what I´d like to get out of elasticsearch is an aggregation on the url field. curl -XGET 'http://localhost:9200/myIndex/_search?pretty' -d '{ "facets": { "groupByMyUrlField": { "terms": { "field": "myUrlField" } } } }' This is all well and good, but the default analyzer tokenizes the field so that each part of the url is a token, so I get hits for http , google.com , foo and bar . But

Using escaped_list_separator with boost split

由 感情迁移 提交于 2019-12-06 05:26:03
问题 I am playing around with the boost strings library and have just come across the awesome simplicity of the split method. string delimiters = ","; string str = "string, with, comma, delimited, tokens, \"and delimiters, inside a quote\""; // If we didn't care about delimiter characters within a quoted section we could us vector<string> tokens; boost::split(tokens, str, boost::is_any_of(delimiters)); // gives the wrong result: tokens = {"string", " with", " comma", " delimited", " tokens", "\

Tokenize .htaccess files

由 走远了吗. 提交于 2019-12-05 16:31:44
Bet you didn't see this coming? ;) So, a project of mine requires that I specifically read and make sense out of .htaccess files . Sadly, searching on Google only yields the infinite woes of people trying to get their own .htaccess to work (sorry, couldn't resist the comment). Anyway, I'm a bit scared of trying to get this thing out of open-source projects that use it. See, in the past few weeks, I ended up wasting a lot of time trying to fix my issues with this strategy, only to find out that I did better to read RFCs & specs and build the thing my way. So, if you know about a library, or any
