Package: rer.solrpush
Product that allows SOLR indexing/searching of a Plone website.SOLR schema configurationThis product works with some assumptions and SOLR schema need to have some particular configuration.You can see an example in config folder of this product.By default we mapped all base Plone indexes/metadata into SOLR, plus some additional fields:<field name="searchwords" type="string" indexed="true" stored="true" required="false" multiValued="true" termVectors="false" termPositions="false" termOffsets="false"/>
<field name="showinsearch" type="boolean" indexed="true" stored="false" required="false" multiValued="false" termVectors="false" termPositions="false" termOffsets="false"/>
<field name="url" type="string" indexed="false" stored="true" required="false" multiValued="false" termVectors="false" termPositions="false" termOffsets="false"/>
<field name="site_name" type="string" indexed="true" stored="true" required="false" multiValued="false" termVectors="false" termPositions="false" termOffsets="false"/>

<field name="path_parents" type="string" indexed="true" stored="true" multiValued="true"/>
<field name="view_name" type="string" indexed="true" stored="true" required="false" multiValued="false" termVectors="false" termPositions="false" termOffsets="false"/>

It basically indicates that schema.xml has been loaded.index_fields: is the list of SOLR fields loaded from schema.xml file.schema.xml loadSOLR fields are directly read fromschema.xmlfile exposed by SOLR.This schema is stored in Plone registry for performance reasons
and is always synced when you savesolr-controlpanelform
or click onReload schema.xmlbutton.File indexingIf 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.Filecontent-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 indexedN.B.:SearchableTextindex should bemultivalued.Search configurationIn 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^500.0You can also elevate bysearchwords.bqspecifies 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 specificsearchwordsterm:searchwords:something^1000Solr will improve ranking for results that have “something” in their searchwords field.bfspecifies 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.
Anyfunction supported nativelyby 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_depthis an index that counts tree level of an object.CollectionsThere are two new Collection’s criteria that allows to search on SOLR also in Collections:Search with SOLR: if checked, searches will be redirected to SOLR (the default is always on local Plone Site).Sites: a list of indexes plone sites on SOLR. The user can select on which sites perform the query.
If no sites are set (or this criteria not selected), the default search will be made only in the current site.There is also a customized querybuilder that perform queries to SOLR or to Plone catalog.Results from SOLR are wrapped into some brain-like objects to be fully compatible with Collection views.Development buildoutIn the buildout there is a solr configuration (inconffolder) and a recipe that builds a solr instance locally.To use it, simply run:> ./bin/solr-foregroundInstallationAdd rer.solrpush to buildout:[buildout]
