title: Appropriate Database to store 20 GB for Delphi, Firemonkey
body: <p>I don't have experience in database development, so I need your suggestions in choosing of a database that can be used in <code>Firemonkey</code>.</p>
  
  <p>I need to store html files (without media now, but they can be with), their total size is around 20 GB (uncompressed text). A main feature must be maximally fast searching of text in the database, and it must be possible to implement human searching (like google). Plus, there can be compression (20 GB is to much to store. If compression makes searching slow it's not required).</p>
  
  <p>What kind of databases are appropriate for my concern?
  Thanks a lot for your suggestions!</p>

  <p>I know an on-line web legal database that can search words through 100 GB of information in milliseconds. I need the same performance, and Google-like searching is required.</p>
