Appendix A: FTS Configuration File
The full text search configuration file is an XML file, which is usually located in the
src directory of the core module and contains the description of indexed entities and their attributes.
The set of FTS configuration files, including those defined in the base projects, is specified in the cuba.ftsConfig application property.
The file has the following structure:
fts-config - root element.
entities- list of entities to be indexed and searched.
entity - indexed entity description.
class- entity Java class.
show- defines whether this entity should appear in the search results. The
falsevalue is used for connecting entities which are not of interest to the user, but are required, for example, to link uploaded files and entities of the domain model. Default is
include- determines whether to include a single or multiple entity attributes in the index.+
re- regular expression to select attributes by name.
name- attribute name. It can be reference attributes path (divided by period). The type is not checked. However, if the name is defined by a path, then the final attribute must be an entity. Including non-entity type attribute does not make sense here, as it must be indexed within its owning entity.
exclude- excludes attributes previously included by
includeelement. Possible attributes are the same as in include.
searchables- a Groovy script to add arbitrary entities associated with the changed one to the indexing queue.
For example, when a
CardAttachmentinstance is either added or removed, the associated
Cardinstance should also be re-indexed. The reason is that the
Cardinstance itself will not be added to the queue, as it has not been changed (it stores a collection of
CardAttachmentinstances). Thus it will not be shown in search results if matching data is found in its linked entity - a newly added
The following objects are passed into the script at invocation:
searchables- the list of entities that should be appended.
entity- the current entity instance, which is being added to the queue automatically.
<entity class="com.haulmont.workflow.core.entity.CardAttachment" show="false"> ... <searchables> searchables.add(entity.card) </searchables> </entity>
searchableIf- a Groovy script to exclude certain instances of the indexed entity from the queue.
For example, you may not want to index old versions of documents.
When running the script, the
entityvariable - the current entity instance - is passed into it. The script should return a boolean value:
trueif the current instance should be indexed, and
<entity class="com.haulmont.docflow.core.entity.Contract"> ... <searchableIf> entity.versionOf == null </searchableIf> </entity>
FTS configuration file example:
<fts-config> <entities> <entity class="com.sample.library.entity.Author"> <include re=".*"/> </entity> <entity class="com.sample.library.entity.Book"> <include re=".*"/> </entity> <entity class="com.sample.library.entity.BookInstance"> <include re=".*"/> </entity> <entity class="com.sample.library.entity.BookPublication"> <include re=".*"/> </entity> <entity class="com.sample.library.entity.Publisher"> <include re=".*"/> </entity> <entity class="com.sample.library.entity.EBook"> <include name="publication.book"/> <include name="attachments.file"/> </entity> <entity class="com.haulmont.workflow.core.entity.CardAttachment" show="false"> <include re=".*"/> <exclude name="card"/> <searchables> searchables.add(entity.card) </searchables> </entity> </entities> </fts-config>
