search

问题 I have a Solr index with many entries, and upon query some subset is returned - each entry having some score, (Obvious). Once the results are returned with scores, I want to be able to only "keep" results that are above some score (i.e. results of a certain quality only). Is it possible to do this when the returned subset could be anything? I ask because it seems like on some queries a score of say 0.008 is resulting in a decent match, whereas other queries a higher score results in a poor

问题 I want to know how I could perform some kind of index on keys from a python dictionary. The dictionary holds approx. 400,000 items, so I am trying to avoid a linear search. Basically, I am trying to find if the userinput is inside any of the dict keys. for keys in dict: if userinput in keys: DoSomething() break That would be an example of what I am trying to do. Is there a way to search in a more direct way, without a loop ? or what would be a more efficient way. Clarification: The userinput

问题 I'm working trying to automatically categorize short articles and I'm trying to figure out how to match similar words - eg, shelf shelves or painting and repaint I'm using the Porter stemming algorithm but it only helps for certain situations and only with the end of the word (both examples above don't work with it). Is there an algorithm or related word lists that would help with something like this (outside of making my own?) (I'm working in php so any solutions in that language would be

问题 I'm making a ListView with data I get from a database placed in a server. The ListView has TWO TextViews for each row, one for the cities, and the other one for the ID's each city has on the database, but this textview(the ID's one) is HIDDEN from the ListView, so the user can only see cities. Everything works fine, but now I want to add a search bar to the listview so I can filter the cities, but i'm getting the following problems: 1.-The adapter of the ListView is a Simple Adapter, as you

问题 I've got typeahead working just fine, but I am too inexperienced with the Javascript to understand how to turn the typed results into a link. <input type="text" class="span3" data-provide="typeahead" placeholder="City Search:" data-items="6" autocomplete="off" data-source=["Neuchatel","Moutier"]"> So, I really just want to know how to turn the strings from data-source into links to other pages. Hopefully this is fairly simple. thanks! 回答1: You can turn the strings into links easily.. <input
