Fusion 5.10
    Fusion 5.10

    Lucidworks Fusion

    The Fusion search adapter brokers all communication with the Lucidwork’s Fusion platform using its REST API to query Solr.

    Setup

    To add Fusion search connectors to a Maven project, you must add this dependency to your project’s pom.xml file:

    <dependency>
    <groupId>twigkit</groupId>
    <artifactId>twigkit.fusion</artifactId>
    <version>${project.parent.version}</version>
</dependency>

    Usage

    Assuming you have added the correct dependencies to your project (see above), the Fusion platform configuration can be accessed by pointing to it in the search:platform tag. In this case the platform is placed in a variable named platform using the var attribute, and points to a platform configuration in ../conf/platforms/fusion/search.conf:

    <search:platform var="platform" conf="platforms.fusion.search"></search:platform>

    platforms/fusion/search.conf

    In this example platform configuration, we set some general settings for the platform:

    name: twigkit.search.fusion.Fusion
timeOut: 30000
resultIDField: id
highlight: true
defaultQuery: *:*
query-profile: my-profile

    With a Fusion platform, we also need to set some additional parameters in the following files:

    services/api/fusion.conf

    This file controls which Fusion to use:

    # Hostname of your Fusion
host: myHostname

# Port of your Fusion
port: 6764

# Protocol of your Fusion - e.g. http or https
protocol: http

# Optional: Fusion Authorization mode - native, serviceaccount, or jwt.
#   If not configured, this will default to the first configured option in the order JWT > Service Account > Native
#   Native auth requires no config here, but does require the twigkit.security.provider.fusion module to be loaded.
# auth: native

# Service Account config
userName: admin
password: password

# JWT config
# issuer:
# key:
# groups:

# Optional: If a JWT subject is configured, all requests to Fusion will be sent as the JWT realm user whose name matches the subject
# subject:

    platforms/fusion/social.conf

    This file configures the Lucidworks Appkit Social Module:

    # For every Fusion App, a corresponding YOUR_FUSION_APP_user_prefs collection is automatically created.
# Appkit uses this collection for storing collaboration user-data.

# Name of the collection to store user data in
collection: Supp-Demo_user_prefs

# Name of the Query & Index pipelines to use - _system is the Fusion default
# pipeline: _system

# Enable writing new Social entities into the platform
readOnly: false

# Prevent users from searching this platform directly
webservice-enabled: false

    message/service/fusion.conf

    This file configures how Signals are sent to Fusion:

    # Fusion Signals config

# Name of the Query profile to send Signals through
query-profile: Supp-Demo

# The index pipeline to send Signals to
# signals-index-pipeline: _signals_ingest

# Whether to commit Signals to disk inside Fusion immediately or not
# commit: true

# Whether to index to Fusion asynchronously or not
# async: true

    Required attributes

    query-profile (java.lang.String)
    The Fusion query profile being accessed. If you have created an app via the Fusion UI called MyAwesomeApp, then you will have a default Query Profile called MyAwesomeApp as well - this is a good starting point.
    Applied in: configuration

    Optional attributes

    requestHandler (java.lang.String)
    Name of the Request Handler to use. Use this to specify an alternate Request Handler to use for example, the '/dismax' request handler. Note you can override this by specifying a 'custom' attribute on the query.

    requestMethod (java.lang.String)
    Which HTTP request method to use (GET or POST).

    strategy (java.lang.String)
    Whether to cluster multiple hosts (value should be either combine, or round-robin). To enable sharding, set strategy to combine.

    groupField (java.lang.String)
    Setting this enables Solr Result Grouping or Field Collapsing on the given field. This will create a Result for each Group returned. Matching documents for the group will be available as related results.

    timeOut (java.lang.Integer)
    Time out for platform query requests (in milliseconds).
    Default: 5000

    ignoreAppliedFilters (java.lang.Boolean)
    If this is set to false, facet filters that have already been applied to the Query are added to the list of filters for the facet.
    Default: true

    backwardsCompatible (java.lang.Boolean)
    For Solr 1.x (for example, 1.4) set backwardsCompatible to true.
    Default: false

    highlight (java.lang.Boolean)
    Whether to enable hit highlighting (hl parameter) in Solr.
    Default: true

    Attributes shared across platforms

    aliases (java.lang.String)
    Manage mappings from field names to aliases (use a comma-separated list). All references to the field (via this platform) in results, facets, filters, and query strings are mapped. For example, to refer to a field in the index named firstnamelastname as name and countryofresidence as country, use these mappings: aliases="firstnamelastname=name,countryofresidence=country"

    defaultQuery (java.lang.String)
    Default query to use when none is specified. For Solr use : to bring back all items (for example, for 'zero term search').

    defaultFacets (java.lang.String)
    Default facets to request when none are specified. This is a comma separated list.

    spellCheck (java.lang.Boolean)
    Spellcheck the Query term if supported by the Platform.
    Default: true

    expandQuery (java.lang.Boolean)
    Apply advanced linguistics such as stemming or lemmatization if supported by the Platform.
    Default: true

    autoCorrect (java.lang.Boolean)
    Whether to auto-correct and resubmit futile queries (queries with zero results).
    Default: true

    fileTypeField (java.lang.String)
    Set which field contains information about file type (mime type).
    Applied in: configuration

    resultIDField (java.lang.String)
    Set which field represents the unique identifier for a given result. Should correspond to the <uniqueKey> element in the Solr schema.xml.
    Applied in: JSP tag, configuration

    pageLimit (java.lang.Long)
    A limitation to which page the platform will offset.
    Applied in: JSP tag, configuration

    Hit highlighting

    Hit highlighting is enabled by default, and assumes that the unique uniqueKey field in the Solr schema.xml file is named id. If your uniqueKey is set to a different field highlighting will not work unless you set the resultIDfield key in the Appkit configuration to the right field.

    resultIDField = yourUniqueKey

    Appkit expects that Solr’s default highlighting tags of <em></em> are used. Ensure that this has not been set to something different using hl.simple.pre and hl.simple.post settings in the Solr or request handler configurations.
