You can do: git log -S <search string> –source –all To find all commits that added or removed the fixed string search string. The –all parameter means to start from every branch and –source means to show which of those branches led to finding that commit. It’s often useful to add -p to show the … Read more
The best way to implement a RESTful search is to consider the search itself to be a resource. Then you can use the POST verb because you are creating a search.

EDIT: From your comment it looks like you want to list all lines without … Read more

As the re.match documentation says: If zero or more characters at the beginning of string match the regular expression pattern, return a corresponding MatchObject instance. Return None … Read more
You can use a generator expression: >>> dicts = [ … { “name”: “Tom”, “age”: 10 }, … { “name”: “Mark”, “age”: 5 }, … { “name”: “Pam”, “age”: 7 }, … { “name”: “Dick”, “age”: 12 } … ] >>> next(item for item in dicts if item[“name”] == “Pam”) {‘age’: 7, ‘name’: ‘Pam’} If … Read more
Assuming that “integer” means 32 bits: 10 MB of space is more than enough for you to count how many numbers there are in the input file with any given 16-bit prefix, for all possible 16-bit prefixes in one pass through the input file. At least one of the buckets will have be hit less … Read more
Update Now that the question scope has been corrected, I might add something in this regard as well: There are many comparisons between Apache Solr and ElasticSearch available, so I’ll reference those I found most useful myself, i.e. covering the most important aspects: Bob Yoplait already linked kimchy’s answer to ElasticSearch, Sphinx, Lucene, Solr, Xapian. … Read more
If you want to find all commits where the commit message contains a given word, use $ git log –grep=word If you want to find all commits where “word” was added or removed in the file contents (to be more exact: where the number of occurrences of “word” changed), i.e., search the commit contents, use … Read more
