Overview and Benefits

Rubicon is a Delphi/C++Builder add-on that lets you put full text search capabilities into your Windows applications.

You retain control of all data, including all the content and all the indexing.

Beginner to advanced search expressions are supported.... from simple wildcard queries to complex expressions.

One system works with all major database bridges used by Delphi and C++Builder programmers including FireDAC, ADO, IB Express, NexusDB, IBObjects, ElevateDB and others.

Is Rubicon for me, now?

Facts about Rubicon Searches

End-users can search using wildcards and Boolean logic against tables, text, RTF, and HTML files. Results may be ranked and matching words automatically highlighted. A hints control displays matching words and the number of hits as the surfer types. Supports multi-table searches with tables of identical or different record structures. Most searches take less than 1/10th of a second and do not require reading the source data as Rubicon pre-builds its own index data. These indexes may be built and updated by using threads and/or multiple PCs.

FREE Demo Info / Screenshots

Stream the Rubicon Showcase On-Demand to quickly see what Rubicon can do for a desktop Windows application. In the showcase, we use FireDAC and Rubicon Bridge K to search a database of 173,000 recipes.

Delphi source code for the Rubicon showcase project is available, even in Rubicon Lite. After installing, look in the r_samples\demo_k_firedac folder for sample projects for use with Delphi and FireDAC.
