Or if you want to find both strings even when they are not right next to each other, pipe your greps together, like this:
grep Feb /usr/file | grep 09
This would find it even if the exact text isn't Feb 09 but both pieces are on the same line. For example, it would find "Today is Feb 09" but it would also find "My grandfather was born in February 1909". The method blowtorch suggested is better if you want to find just the exact string Feb 09.
Ok, I just noticed the line where you said they need to be separated by one space, so I guess blowtorch's method is better. But I might as well leave this here for more information since I bothered to type it in. :-)

NAME
lookbib - find references in a bibliographic database
SYNOPSIS
lookbib database
DESCRIPTION
A bibliographic reference is a set of lines, constituting fields of bibliographic information. Each field starts on a line beginning with
a `%', followed by a key-letter, then a blank, and finally the contents of the field, which may continue until the next line starting with
`%'.
The lookbib utility uses an inverted index made by indxbib to find sets of bibliographic references. It reads keywords typed after the `>'
prompt on the terminal, and retrieves records containing all these keywords. If nothing matches, nothing is returned except another `>'
prompt.
It is possible to search multiple databases, as long as they have a common index made by indxbib(1). In that case, only the first argument
given to indxbib is specified to lookbib.
If lookbib does not find the index files (the .i[abc] files), it looks for a reference file with the same name as the argument, without the
suffixes. It creates a file with a .ig suffix, suitable for use with fgrep (see grep(1)). lookbib then uses this fgrep file to find refer-
ences. This method is simpler to use, but the .ig file is slower to use than the .i[abc] files, and does not allow the use of multiple
reference files.
FILES
x.ia
x.ib
x.ic index files
x.ig reference file
