jQuery DataTables - Filter column by exact match

自作多情 提交于 2019-12-27 22:14:49
问题 Trying to only display exact matches to the search term entered in the search bar. For instance, I have a search bar that filters by ID#. I want only records that match the exact # entered to display. So if 123 is entered, I don't want 12345 , 91239 , etc etc to be displayed. Only 123 . Saw some info about bRegex on the FAQ page, but it's not working for me. Any ideas? 回答1: This will give you exact result for a column. table.column(i) .search("^" + $(this).val() + "$", true, false, true)

Fastest way to search a list in python

て烟熏妆下的殇ゞ 提交于 2019-12-27 17:37:12
问题 When you do something like "test" in a where a is a list does python do a sequential search on the list or does it create a hash table representation to optimize the lookup? In the application I need this for I'll be doing a lot of lookups on the list so would it be best to do something like b = set(a) and then "test" in b ? Also note that the list of values I'll have won't have duplicate data and I don't actually care about the order it's in; I just need to be able to check for the existence

Partial matching GAE search API

我的梦境 提交于 2019-12-27 17:32:51
问题 Using the GAE search API is it possible to search for a partial match? I'm trying to create autocomplete functionality where the term would be a partial word. eg. > b > bui > build would all return "building". How is this possible with GAE? 回答1: Though LIKE statement (partial match) is not supported in Full Text Search, but you could hack around it. First, tokenize the data string for all possible substrings (hello = h, he, hel, lo, etc.) def tokenize_autocomplete(phrase): a = [] for word in

SQL Between clause with strings columns

隐身守侯 提交于 2019-12-27 14:56:54
问题 I want to make a search using "between" clause over a string column. Doing some test I got this: Let's assume that there is a country table with a "name" column of type varchar. If I execute this query: Select * from country where name between 'a' and 'b' I got this result: Argentina . . . Argelia. It excludes those countries that starts with B which I found a little bit weird. Is there a way to do this search in a more accurate way? Any other ideas for make this search? Thanks in advance 回答1

Which SQL query is better, MATCH AGAINST or LIKE?

好久不见. 提交于 2019-12-27 13:10:05
问题 To search the database for rows that have both keywords "foo" AND "bar" in any of the columns "foo_desc" and "bar_desc", I would do something like: SELECT * FROM t1 WHERE MATCH (t1.foo_desc, t2.bar_desc) AGAINST ('+foo* +bar*' IN BOOLEAN MODE) or SELECT * FROM t1 WHERE (CONCAT(t1.foo_desc, t2.bar_desc) LIKE '%foo%') AND (CONCAT(t1.foo_desc, t2.bar_desc) LIKE '%bar%') I expect the downside of the last query is performance. The upside is that the LIKE query finds 'xxfoo' where MATCH AGAINST
