Hyper Estraier is a full-text search system for communities.
This is a package implementing the core API of Hyper Estraier, including native codes written in C. As it works on Linux, Mac OS X, Windows, and so on, native libraries for each environment are required to run programs. This package requires Ruby 1.8.4 or later versions.
Install the latest version of Hyper Estraier.
Enter the sub directory `rubynative’ in the extracted package then perform installation.
cd rubynative ./configure make su make install
The package `estraier’ should be required in each source file of application programs and include the module `Estraier’ at pleasure.
The following is the simplest implementation of a gatherer.
require "estraier" include Estraier # create the database object db = Database::new # open the database unless db.open("casket", Database::DBWRITER | Database::DBCREAT) printf("error: %s\n", db.err_msg(db.error)) exit end # create a document object doc = Document::new # add attributes to the document object doc.add_attr("@uri", "http://estraier.gov/example.txt") doc.add_attr("@title", "Over the Rainbow") # add the body text to the document object doc.add_text("Somewhere over the rainbow. Way up high.") doc.add_text("There's a land that I heard of once in a lullaby.") # register the document object to the database unless db.put_doc(doc, Database::PDCLEAN) printf("error: %s\n", db.err_msg(db.error)) end # close the database unless db.close printf("error: %s\n", db.err_msg(db.error)) end
