Finding is the completion of searching. If you might not succeed in finding something, call the feature “Search”. For example text search in an editor can fail due to no matches – then calling it “Find” would be lying. On the other hand: in an established job searching site, you can say “Find a PHP … Read more
RavenDB: It has Lucene built-in for your full-text searches. It can be replicated. It supports sharding. It has a HTTP API so you can in principle use it from any platform. Cons: it’s AGPL licensed. Depending on your dev/server environment, you could consider it running on .NET a con. Also I’m not aware of the … Read more
Don’t create a list, create a set. It does lookups in constant time. If you don’t want the memory overhead of a set then keep a sorted list and search through it with the bisect module. from bisect import bisect_left def bi_contains(lst, item): “”” efficient `item in lst` for sorted lists “”” # if item … Read more
I have been spending many time for this but finally: 🙂 To change the text color : ((EditText)searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text)).setTextColor(Color.WHITE); or this one for AndroidX: ((EditText)searchView.findViewById(androidx.appcompat.R.id.search_src_text)).setTextColor(Color.WHITE); To change the text hint: ((EditText)searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text)).setHintTextColor(Color.WHITE); or this one for AndroidX: ((EditText)searchView.findViewById(androidx.appcompat.R.id.search_src_text)).setHintTextColor(Color.WHITE);
You could make a terms facet on your ‘full_name’ field. But in order to do that properly you need to make sure you’re not tokenizing it while indexing, otherwise every entry in the facet will be a different term that is part of the field content. You most likely need to configure it as ‘not_analyzed’ … Read more
No, there is no built-in method to do that. But, directly copied from HERE (with two fixes applied to the original code): /** * Knuth-Morris-Pratt Algorithm for Pattern Matching */ class KMPMatch { /** * Finds the first occurrence of the pattern in the text. */ public static int indexOf(byte[] data, byte[] pattern) { if … Read more
The simplest way without editing any Meteor code is to use your own mongodb. Your mongodb.conf should look something like this (on Arch Linux it is found at /etc/mongodb.conf) bind_ip = 127.0.0.1 quiet = true dbpath = /var/lib/mongodb logpath = /var/log/mongodb/mongod.log logappend = true setParameter = textSearchEnabled=true The key line is setParameter = textSearchEnabled=true, which, … Read more
You can do better than O(log n) if the values are integers, in which case the best worst-case running time you can achieve, in terms of n, is O(sqrt(log n)). Otherwise, there is no way to beat O(log n) unless there are patterns in the input sequence. There are two approaches used to beat O(log … Read more
Yes, you can: irb(main):002:0> s1 = “foo” #=> “foo” irb(main):003:0> s2 = ObjectSpace._id2ref(s1.object_id) #=> “foo” irb(main):004:0> s2.object_id == s1.object_id #=> true irb(main):005:0> s2[0] = “z” #=> “z” irb(main):006:0> s1 #=> “zoo” Should you do this? I’ll leave that up to you. There are less geeky ways to store an object with a serializable id (e.g. … Read more
You can create a new column for the difference > df[‘C’] = df[‘B’].diff() > print df # A B C 0 1 2 3 NaN 1 2 3 3 0 2 3 4 4 1 3 4 5 4 0 4 5 5 4 0 > df_filtered = df[df[‘C’] != 0] > print df_filtered # … Read more
