While they were no ‘full blown’ releases (i.e. full documentation, web site updates) of Lucene.Net for quite some time, there are still fresh commits to its SVN repository. The latest release (2.3.2) for example was tagged in 07/24/09 (see here). Since the development is still active I would use it for new full-text-search projects.
ughoavgfhw offered the correct answer (above). Use Cmd+E on the selected text to begin searching with that text. Then immediately type Cmd+Shift+F to search the whole project for all instances of the text hit enter. This is quite quick, consistent, and sensible.

a_href = a_href.replace(/(test_ref=)[^\&]+/, ‘$1’ + updated_test_ref);
You can give a try to Apache Commons Collections. There is a class CollectionUtils that allows you to select or filter items by custom Predicate. Your code would be like this: Predicate condition = new Predicate() { boolean evaluate(Object sample) { return ((Sample)sample).value3.equals(“three”); } }; List result = CollectionUtils.select( list, condition ); Update: In java8, … Read more
Variant 1 is great if you need to launch many sequential searches. Since set is internally a hash table, it’s rather good at search. It takes time to build, though, and only works well if your data fit into RAM. Variant 3 is good for very big files, because you have plenty of address space … Read more
Yes, you can use SQL IN operator to search multiple absolute values: SELECT name FROM products WHERE name IN ( ‘Value1’, ‘Value2’, … ); If you want to use LIKE you will need to use OR instead: SELECT name FROM products WHERE name LIKE ‘%Value1’ OR name LIKE ‘%Value2’; Using AND (as you tried) requires … Read more
If you set the index to the ‘Group’ column on the other df then you can replace using map on your original df ‘Group’ column: In [36]: df[‘Group’] = df[‘Group’].map(df1.set_index(‘Group’)[‘Hotel’]) df Out[36]: Date Group Family Bonus 0 2011-06-09 Jamel Laavin 456 1 2011-07-09 Frank Grendy 679 2 2011-09-10 Luxy Fantol 431 3 2011-11-02 Frank Gondow … Read more
find . only looks in your current directory. If you have permissions to look for files in other directories (root access) then you can use the following to find your file – find / -type f -name “*.jdk” If you are getting tons of permission denied messages then you can suppress that by doing find … Read more
Here’s one way to do it: if not any(d[‘main_color’] == ‘red’ for d in a): # does not exist The part in parentheses is a generator expression that returns True for each dictionary that has the key-value pair you are looking for, otherwise False. If the key could also be missing the above code can … 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
