Bruce Payette, co-founder of PowerShell, gave a talk on integrating full-text search using Lucene with PowerShell at the PowerShell Summit.

Refactoring

So I did a little refactoring and wrapped it in GUI, this is all PowerShell.

In Action

It indexed the content of 2500+ files in ~2 seconds.

Index and Search

Type in the name of the directory to be searched, including a filter, c:\posh\*.ps1 , press enter and it will recursively search the directory for all ps1 files and index the contents, keeping the index in memory. You can also search multiple directories with different filters. E.g. c:\temp\*.cs , c:\test\*.ts , c:\arm\*.json

Then, you can search for a term across everything that was indexed by typing in the Query box and pressing enter.
