type - string
Fully qualified class name of ConnectorDb implementation.
>= 1 characters
Default: com.lucidworks.connectors.db.impl.MapDbConnectorDb
inlinks - boolean
Keep track of incoming links. This negatively impacts performance and size of DB.
Default: false
aliases - boolean
Keep track of original URI-s that resolved to the current URI. This negatively impacts performance and size of DB.
Default: false
inv_aliases - boolean
Keep track of target URI-s that the current URI resolves to. This negatively impacts performance and size of DB.
Default: false
startLinks - array[string]
To crawl all of the files owned by the account, simply add ‘/’ as the start link; otherwise, use a path to the specific files or directories that you want to crawl, e.g., https://www.dropbox.com/home/Test_files/test_basic_crawl
dedupe - boolean
If true, documents will be deduplicated. Deduplication can be done based on an analysis of the content, on the content of a specific field, or by a JavaScript function. If neither a field nor a script are defined, content analysis will be used.
Default: false
dedupeField - string
Field to be used for dedupe. Define either a field or a dedupe script, otherwise the full raw content of each document will be used.
dedupeScript - string
Custom javascript to dedupe documents. The script must define a 'genSignature(content){}' function, but can use any combination of document fields. The function must return a string.
dedupeSaveSignature - boolean
If true,the signature used for dedupe will be stored in a 'dedupeSignature_s' field. Note this may cause errors about 'immense terms' in that field.
Default: false
delete - boolean
Set to true to remove documents from the index when they can no longer be accessed as unique documents.
Default: true

Default: 5
emitThreads - integer
The number of threads used to send documents from the connector to the index pipeline. The default is 5.

chunkSize - integer
The number of items to batch for each round of fetching. A higher value can make crawling faster, but memory usage is also increased. The default is 1.
Default: 1
fetchDelayMS - integer
Number of milliseconds to wait between fetch requests. The default is 0. This property can be used to throttle a crawl if necessary.
Default: 0
refreshAll - boolean
Set to true to always recrawl all items found in the crawldb.
Default: true
refreshStartLinks - boolean
Set to true to recrawl items specified in the list of start links.
Default: false

Number of seconds to recrawl items whose last fetched date is longer ago than this value.
Default: -1
refreshIDPrefixes - array[string]
A prefix to recrawl all items whose IDs begin with this value.
refreshIDRegexes - array[string]

refreshScript - string
A JavaScript function ('shouldRefresh()') to customize the items recrawled.
forceRefresh - boolean
Set to true to recrawl all items even if they have not changed since the last crawl.
Default: false
forceRefreshClearSignatures - boolean
If true, signatures will be cleared if force recrawl is enabled.
Default: true
retryEmit - boolean
Set to true for emit batch failures to be retried on a document-by-document basis.
Default: true
depth - integer
Number of levels in a directory or site tree to descend for documents.

crawlDBType - string
The type of crawl database to use, in-memory or on-disk.
Default: on-disk
Allowed values: in-memoryon-disk
commitAfterItems - integer
Commit the crawlDB to disk after this many items have been received. A smaller number here will result in a slower crawl because of commits to disk being more frequent; conversely, a larger number here will cause a resumed job after a crash to need to recrawl more records.
Default: 10000
initial_mapping - Initial field mapping
Provides mapping of fields before documents are sent to an index pipeline.
skip - boolean
Set to true to skip this stage.
Default: false
label - string
A unique label for this stage.
<= 255 characters
condition - string
Define a conditional script that must result in true or false. This can be used to determine if the stage should process or not.
reservedFieldsMappingAllowed - boolean
Default: false
retentionMappings - array[object]
Define here which fields should be kept or deleted
Default:
object attributes:{field required : {
display name: Field
type: string
}operation : {
