Usage

First, instantiate the KalturaReader (aka Kaltura Loader) with your Kaltura configuration credentials:

python

from llama_index.readers.kaltura_esearch import KalturaESearchReader

loader = KalturaESearchReader(
    partnerId="INSERT_YOUR_PARTNER_ID",
    apiSecret="INSERT_YOUR_ADMIN_SECRET",
    userId="INSERT_YOUR_USER_ID",
)

Using an instance of KalturaESearchEntryParams

Then, create an instance of KalturaESearchEntryParams and set your desired search parameters:

python

from KalturaClient.Plugins.ElasticSearch import (
    KalturaESearchEntryParams,
    KalturaESearchEntryOperator,
    KalturaESearchOperatorType,
    KalturaESearchUnifiedItem,
)

# instantiate the params object
search_params = KalturaESearchEntryParams()

# define search parameters (for example, search for entries with a certain tag)
search_params.searchOperator = KalturaESearchEntryOperator()
search_params.searchOperator.operator = KalturaESearchOperatorType.AND_OP
search_params.searchOperator.searchItems = [KalturaESearchUnifiedItem()]
search_params.searchOperator.searchItems[0].searchTerm = "my_tag"

Once you have your KalturaESearchEntryParams ready, you can pass it to the Kaltura Loader:

python

# Using search params
entry_docs = loader.load_data(search_params)

Using Free Text Search

python

# Simple pass the search params into the load_data method without setting search_params
entry_docs = loader.load_data(
    search_operator_and=True,
    free_text="education",
    category_ids=None,
    with_captions=True,
    max_entries=5,
)

This loader is designed to be used as a way to load data into LlamaIndex.
