As web technologies have evolved, so has the sophistication of the EDGAR database. With the EDGAR database, you can:
Search for company reports since 1994 using a convenient search form . . .
The following parameters are allowed:
Company Name
Ticker Symbol
State
Country
SIC Code [Note: NAICS is not used]
Search the header fields of company documents (except the most recent day) using Boolean operators (AND, OR, NOT, etc) using this search form . . .
Review a list of only the most recent filings . . .
The SEC also provides both quick and in-depth tutorials for how to search EDGAR.
