# Help Search Expressions

Each help context should be associated with a context-specific help search expression, which the Eclipse help system will use to provide Dynamic Help search results in the Help view.

Documentation teams are responsible for defining the context-specific help search expressions for each help context.

Additional considerations:

- Each help search expression can be associated with multiple help context IDs, but
  - Each helpKey constant must be associated with exactly one help search expression.
- Each help context within a UI component (for example, a UI plug-in) can be associated with a unique help search expression, however
  - It may be more practical to define a “generic” help search expression for each UI component, which would limit search results to product-specific content, rather than including all of the help content contributed by any doc plug-in.

For each helpKey constant, the help context should be defined before the help search expression is defined. If the Documentation team chooses to combine multiple helpKey constants in a single help context, all of the helpKey constants associated with that help context should be associated with the same search expression.
