Presentation of the Advanced Search Tool
The advanced search tool (Query Tool) is available:
from the workspace, using the of the search toolbar.
from other HOPEX tools such as diagrams, the explorer, etc.
Different modes, each corresponding to a tab, are available depending on how the search is run (from the workspace or from another tool).
Use the advanced search tool to enter queries, which define:
the objects and links browsed.
the conditions on links and objects making up the repository browsing path.
The subject of the search is called “target”.
A query can be written:
using a wizard: see "Querying Using the Query Assistant".
directly using the repository query language (ERQL)
*ERQL (Entity Relationship Query Language) enables you to define queries using entity/relationship formalism.
For information on this language syntax, see "Query Syntax".
Querying from the workspace
In your HOPEX (Windows Front-End) workspace, you can search objects via:
the search toolbar to run a quick search
*See "The Quick Search (Windows Front-End)".
the advanced search tool (click ) which offers a number of search modes:
Assistant
*See "Querying Using the Query Assistant".
Recent queries
*See "Using Recent Queries".
Registered queries

Searching from another HOPEX tool
The search tool can be called from numerous HOPEX windows or tools (explorer, diagram, etc.).
For example it can be called from a diagram if you want to add an object.
When run from another HOPEX tool, the search toolbar includes the following tabs in addition to the three standard modes:
Candidates (see "Handling Candidate Objects")
Result (see "Query Result")
