rer.solrpush 1.4.3

Hidden registry fields

There are some “service” registry fields hidden to disallow users to edit them.

• ready: a flag that specifies if the product is ready/initialized. It basically indicates that schema.xml has been loaded.

• index_fields: is the list of SOLR fields loaded from schema.xml file.

schema.xml load

SOLR fields are directly read from schema.xml file exposed by SOLR.

This schema is stored in Plone registry for performance reasons and is always synced when you save solr-controlpanel form or click on Reload schema.xml button.

File indexing

If Tika is configured on SOLR, you can send attachments to it and they will be indexed as SearchableText in the content.

To allow attachments indexing, you need to register an adapter for each content-type that you need to index.

File content-type is already registered, so you can copy from that:

<adapter
  for="plone.app.contenttypes.interfaces.IFile"
  provides="rer.solrpush.interfaces.adapter.IExtractFileFromTika"
  factory=".file.FileExtractor"
  />

from rer.solrpush.interfaces.adapter import IExtractFileFromTika
from zope.interface import implementer


@implementer(IExtractFileFromTika)
class FileExtractor(object):
    def __init__(self, context):
        self.context = context

    def get_file_to_index(self):
        """
        """
        here you need to return the file that need to be indexed

N.B.: SearchableText index should be multivalued.

Search configuration

In solr controlpanel (/@@solrpush-settings) there are some field that allows admins to setup some query parameters.

‘qf’ specifies a list of fields, each of which is assigned a boost factor to increase or decrease that particular field’s relevance in the query.

For example if you want to give more relevance to results that contains searched text into their title than in the text, you could set something like this:

title^1000.0 SearchableText^1.0 description^500.0

You can also elevate by searchwords.

bq specifies an additional, optional, query clause that will be added to the user’s main query to influence the score. For example if we want to boost results that have a specific searchwords term:

searchwords:something^1000

Solr will improve ranking for results that have “something” in their searchwords field.

bf specifies functions (with optional boosts) that will be used to construct FunctionQueries which will be added to the user’s main query as optional clauses that will influence the score. Any function supported natively by Solr can be used, along with a boost value. For example if we want to give less relevance to items deeper in the tree we can set something like this:

recip(path_depth,10,100,1)

path_depth is an index that counts tree level of an object.
