Not the results you expected?

Search Tips

If you have run a search that returned no results there are a few things to try. By default searchcode prioritizes system survival (hey its a free service!), and as such might do some load shedding, which can mean you don't see results you expect. You can do some things to help with this.

Filters

Filtering by language or source will cut down the number of results searchcode needs to look at. If you know a result for instance a term can be found in python code, specifying python re.compile lang:python via the lang:python syntax, or the sidebar filters.

This works in reverse too, if you specify a filter and are not getting what you expect, try removing the filter.

You can also filter by filename database file:content where the filename must match at the start what you supply.

Add more terms or longer terms

Adding more search terms will now only improve relevance it will reduce the number of results that searchcode needs to inspect. So rather than searching for test consider trying unittest or test random.

Keep in mind searchcode uses AND logic. This means search will look for all of the terms you enter split by whitespace. So a search for *testing.T randomstring will look for documents which contain both *testing.T and randomstring in any order in a document, with a preference to displaying snippets where the terms are close together.

Literal search

Searchcode will literal search on anything, split by whitespace. This allows you to search for i++; if you like but it does mean that no advanced search query syntax is supported (for the moment anyway) outside of filters and exact match.

Exact match search

You can search for exact matches by enclosing them in quotes "class ScopSearch(unittest.TestCase):"

Smallest term size

The smallest term you can search for in searchcode is 3 characters long. This is because it uses a trigram index to search on. So a search for two characters, such as i+ will never return a result. However i++ will. Note that while 2 character terms are not searched for if they are in a search with other longer terms it may be used for matching and displaying code snippets.

Case insensitive

Generally consider searchcode case insensitive. It actually lowercase's everything it indexes, so it won't work as expected for some unicode points. Note that highlighting is real unicode case insensitive using simple case fold rules.
