help and examples

Codefetch lets you combine three types of searches:

Google-style Enter words separated by spaces and they'll be found wherever they all appear on a page.

Full-text Like a text editor, Codefetch can find $, {, % or any other ASCII symbol.

Regular Expression You can even use a few regular expression constructs. See table below.

The checkboxes on the result page make it easy. Give them a try!

Whole Words	Surrounds with /b (word boundary regular expression) to avoid fetching compound words.
Literal Phrase	Adds \s (white space regular expression) to fetch literally what you entered, spaces and all.

Currently supported regular expression constructs:

.* Match any character or space or anything or nothing at all.

.+ Match any character or space or anything (but not nothing--there has to be at least one char).

\d+ Match one or more digits.

\s Match one space or tab or other whitespace.

\s+ Match one or more spaces or tabs or other whitespaces.

\b Match a word boundary.

Examples:

foo\b finds foo, tofoo, foo.lish but not foolish or fool_ish

foo bar finds a page with "foolish" then "antibarista", one with "bar" then "foo", and others

foo\b bar\b finds pages with both "foo" and "bar". Also matches "NotAFoo" and "rebar".

foo\s+bar finds "foo bar" and "foo bar" but not "barfoo" or "bar foo".

foo.*bar finds "foobar", "foo blah blah{}bar" but not "barfoo"

port.+\d+ finds lines with "port" and any number of digits following it anywhere on the same line.

<!--.*servers finds "servers" anywhere in an xml comment line.

KEY.*(.*,.*) In SQL, finds examples of multiple keys.
