The Adobe Acrobat Search plug-in allows users to perform text searches in PDF documents. It adds menus, menu items, toolbar button, and a Search panel to the Acrobat viewer.
The Search plug-in exports a Host Function Table (HFT) containing several methods that can be used by other plug-ins.
The HFT’s name is Search, and its version number is 0. To use the Search plug-in’s HFT, a plug-in must include the header file SrchClls.h. The plug-in must also import the HFT using ASExtensionMgrGetHFT and assign the HFT returned by this call to a plug-in-defined global variable named gSearchHFT.
Acrobat 6.0 and later has two versions of the Search plug-in, Search (new in Acrobat 6.0) and Search5 (also available in Acrobat 5.0).
●The Search plug-in uses a search engine licensed from Lextek International. Lextek can be contacted at http://www.lextek.com.
●The Search5 plug-in uses a search engine licensed from Verity, Inc. Verity can be contacted at http://www.verity.com.
You can do the following with either version of the Search plug-in:
–Create or delete indexes

–Ask what indexes are available
–Send queries to an existing index
You cannot use either version of the Search plug-in to directly obtain the results of a search, for manipulation or for display in an application other than Adobe Acrobat.
Search supports interapplication communication (IAC) in the form of Apple events on the Macintosh and DDE messages under the Windows® operating system. These Apple events and DDE messages allow remote clients to submit search queries and manipulate a list of indexes (the list of indexes is referred to as the shelf).
