Ok, I see what’s going on… from the docs: If one or more groups are present in the pattern, return a list of groups; this will be a list of tuples if the pattern has more than one group. As it turns out, you do have a group, “(\d+,?)”… so, what it’s returning is the … Read more
I’d do it like this $referringPage = parse_url( $_SERVER[‘HTTP_REFERER’] ); if ( stristr( $referringPage[‘host’], ‘google.’ ) ) { parse_str( $referringPage[‘query’], $queryVars ); echo $queryVars[‘q’]; // This is the search term used }
You should split the string into words, then loop through the words and increment a counter for each one: var wordCounts = { }; var words = str.split(/\b/); for(var i = 0; i < words.length; i++) wordCounts[“_” + words[i]] = (wordCounts[“_” + words[i]] || 0) + 1; The “_” + allows it to process words … Read more
Not as nice as I hoped for but this oneliner can help out. Notice however that you can’t use * as a filter because the IN function starts selecting files in that case. for %G in (.exe, .dll, .xyz) do forfiles -p “C:abc\del” -s -m *%G -d -70 -c “cmd /c echo @path” Used this … Read more
In your case, I wonder if simply using isset() makes more sense, i.e. isset($a[$key])
This is a very interesting question! I think it depends on the following aspects: accessing single row by index (index is sorted and unique) should have runtime O(m) where m << n_rows accessing single row by index (index is NOT unique and is NOT sorted) should have runtime O(n_rows) accessing single row by index (index … Read more
Depth First Search:
no need for incomplete or unreliable hacks. there’s a function included with python for this >>> import fnmatch >>> fnmatch.translate( ‘*.foo’ ) ‘.*\\.foo$’ >>> fnmatch.translate( ‘[a-z]*.txt’ ) ‘[a-z].*\\.txt$’
Why using a selfmade highlighting function is a bad idea The reason why it’s probably a bad idea to start building your own highlighting function from scratch is because you will certainly run into issues that others have already solved. Challenges: You would need to remove text nodes with HTML elements to highlight your matches … Read more
You should look into the SpellChecker module in the contrib dir. It’s a port of Java lucene’s SpellChecker module, so its documentation should be helpful. (From the javadocs:) Example Usage: import org.apache.lucene.search.spell.SpellChecker; SpellChecker spellchecker = new SpellChecker(spellIndexDirectory); // To index a field of a user index: spellchecker.indexDictionary(new LuceneDictionary(my_lucene_reader, a_field)); // To index a file containing … Read more
