Basic Setup


dynamic_search:
    context:
        default:
            index_provider:
                service: 'lucene'
                options:
                    database_name: 'my_lucene_storage'

Provider Options

Name	Default Value	Description
`database_name`	null
`force_adding_document`	true
`analyzer`	[]

Index Fields

Available Index Fields:

Name	Description
`binary`	Binary fields are not tokenized or indexed, but are stored for retrieval with search hits. They can be used to store any data encoded as a binary string, such as an image icon.
`keyword`	Keyword fields are stored and indexed, meaning that they can be searched as well as displayed in search results. They are not split up into separate words by tokenization.
`text`	Text fields are stored, indexed, and tokenized. Text fields are appropriate for storing information like subjects and titles that need to be searchable as well as returned with search results.
`unIndexed`	UnIndexed fields are not searchable, but they are returned with search hits. Database timestamps, primary keys, file system paths, and other external identifiers are good candidates for UnIndexed fields.
`unStored`	UnStored fields are tokenized and indexed, but not stored in the index. Large amounts of text are best indexed using this type of field. Storing data creates a larger index on disk, so if you need to search but not redisplay the data, use an UnStored field.
