Method and apparatus for generic search interface across document types
View Patent ↗The present invention includes a method and device for generic searching across document types. A further aspect of the present invention is indexing and searching XML documents using an HTML interface generated by a declarative transformation.
1. A computer-implemented method of specifying a search criteria for use by a search engine that searches among a plurality of self-describing, structured documents, said documents including document fields, the method including:
providing a graphical user interface including
a document type selection filter;
at least one document field selection filter, context sensitive to a selected document type;
at least one value specification field, context sensitive to a selected document field; and
as non-displaying fields, one or more path specifications corresponding to the document fields and to the value specification fields, said path specification identifying at least one node to be tested against the completed value specification;
receiving a selected document type, a completed value specification and a corresponding path specification; and
sending a search criteria to a search engine that searches the self-describing, structured documents based on the completed value specification and the corresponding path specification, including documents of the selected document type;
wherein the self-describing, structured documents are XML documents.
2. The method of claim 1 , wherein the path specifications are compliant with an XPath standard.
3. The method of claim 2 , wherein the graphical user interface is compliant with an HTML standard.
4. The method of claim 1 , wherein the graphical user interface is compliant with an HTML standard.
5. A computer-implemented method of specifying a search criteria for use by a search engine that searches among a plurality of self-describing, structured documents, said documents including document fields, the method including:
providing a graphical user interface including
a document type selection filter;
at least one document field selection filter, context sensitive to a selected document type; and
at least one value specification field, context sensitive to a selected document field;
receiving a selected document types, a completed value specification and a document field identifier corresponding to the completed value specification;
looking up a path specification corresponding to the document field identifier, said path specification identifying at least one node to be tested against the completed value specification; and
sending a search criteria to a search engine that searches a subset of the self-describing, structured documents based on the completed value specification and the corresponding path specification, including documents of the selected document type;
wherein the self-describing, structured documents are XML documents.
6. The method of claim 5 , wherein the path specifications are compliant with an XPath standard.
7. The method of claim 6 , wherein the graphical user interface is compliant with an HTML standard.
8. The method of claim 5 , wherein the graphical user interface is compliant with an HTML standard.
9. A method of specifying to a server where to search among a plurality of self-describing, structured documents, said documents having document types and including document fields, the method including:
displaying a graphical user interface including
a document type selection filter;
at least one document field selection filter, context sensitive to a selected document type; and
at least one value specification field, context sensitive to a selected document field;
the graphical user interface further including, as non-displaying fields, at least one path specification corresponding to the selected document field and to a completed value specification field, said path specification identifying at least one node to be tested against the completed value specification;
receiving from a user the selected document type and the completed value specification; and
transmitting to a server the selected document type and the completed value specification and the path specification corresponding to the completed value specification;
wherein the self-describing, structured documents are XML documents.
