Search Tips

By default, a search locates documents containing the search terms specified with the terms that are entered first given more weight than the terms that come after. When you want documents containing any of several words, use commas to separate them.

For example, searching for:

1) "operating permit"

2) operating OR permit

3) operating -permit
