    Web V1 Connector Configuration Reference

    Table of Contents

    The Web connector V1 retrieves data from a Web site using HTTP and starting from a specified URL.

    Fusion uses the Open Graph Protocol as the default configuration for fields. Deviation from that standard configuration may exclude information from indexing during the crawl.

    Configuration

    When entering configuration values in the UI, use unescaped characters, such as \t for the tab character. When entering configuration values in the API, use escaped characters, such as \\t for the tab character.

    Connector for websites and web-based content resources.

    parserId - string

    Parser used when parsing raw content. For some connectors, a configuration to 'retry' parsing if an error occurs is available as an advanced setting

    Default: lucidworks-web

    id - stringrequired

    Unique name for this datasource.

    >= 1 characters

    Match pattern: ^[a-zA-Z0-9_-]+$

    pipeline - stringrequired

    Name of an existing index pipeline for processing documents.

    Datasource configuration properties

    fetchDelayMSPerHost - boolean

    If true, the 'Fetch delay (ms)' property will be applied for each host.

    Default: true

    Default: -1

    restrictToTreeIgnoredHostPrefixes - array[string]

    Modifies the behavior of 'Restrict crawl to start-link tree' to ignore the configured list of prefixes when restricting the crawl. Commonly, 'www.' is ignored so links with the same domain are allowed, whether of the form 'http://host.com' or 'http://www.host.com'. This option requires 'Restrict to start-link tree' to be enabled to have any effect.

    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.

    Default: on-disk

    Allowed values: in-memoryon-disk

    commitAfterItems - integer

    Default: false

    restrictToTreeUseHostAndPath - boolean

    Modifies the behavior of 'Restrict crawl to start-link tree' to include the 'path' of the start link in the restriction logic. For example, if the start link is 'http://host.com/US', this option will limit all followed URLs to ones starting with the '/US/' path.

This gives background JavaScript routines a chance to finish rendering the page before the contents is emitted.

    >= -1

    <= 2147483647

    exclusiveMinimum: false

    exclusiveMaximum: false

    When the requestcounter is enabled, often early on the requestcount may say there are 0 pending requests... but there may still be ajax requests that haven't run yet. This parameter provides a certain time in milliseconds to wait for a non-zero count to be returned. If a requestcount is non-zero at any point, then the next requestcount = 0 is assumed to signify this page is done loading.

    Default: 5000

    f.requestCounterMaxWaitMs - integer
