Solr Indexing - Manipulating the search result - typo3

Question

I am working with the TYPO3 Solr extension and I have some doubts regarding the solr result set manipulation.
I have added a special configuration for indexing some particular pages in my page tree. ie Pages that starts with the label "Expertise%" .I have managed to added this successfully . And the indexing is working successfully with our any trouble. But what I would like to achieve is that , I want to added parent page title to the search result.i.e
This is the page tree
|---- 1.00.100 (parent page)
|--Subpage 1
|--Subpage 2
|--Expertise
|--Test page`
And in the solr search result should be
1.00.100 - Expertise
Is this possible in TYPO3 Solr. Is there any hook or signalslot available to implement this?
Tried this ,But doesn't seems to work for me ?
plugin.tx_solr.index.queue.expertise_offered = 1
plugin.tx_solr.index.queue.expertise_offered {
table = pages
additionalWhereClause = doktype = 1 AND no_search = 0 AND title LIKE '%Expertise offered%'
fields {
title = title
content = CONTENT
parentPageTitle_stringS = CONTENT
parentPageTitle_stringS {
table = pages
select {
selectFields = title
where = uid = ###pid###
}
markers {
pid.data = field:pid
}
}
content {
table = tt_content
select {
selectFields = header, bodytext
}
renderObj = COA
renderObj {
10 = TEXT
10.field = header
# This removes HTML tags
11 = SOLR_CONTENT
11.field = bodytext
}
}
url = TEXT
url.typolink.parameter = TEXT
url.typolink.parameter.field = uid
}
}

You probably don't need any hook or signal-slot. You can do it as follows:
Add the title of the parent page to your indexing configuration. There is no field for it, but you can dynamically add fields to SOLR documents. This is done by sending the data in a field which has a certain suffix, which determines the field type.
For example: Setting the field parentPageTitle_stringS to the parent pages title in the indexing configuration creates a new stored, single-valued field of type string in the indexed document.
Filling this field could look like this:
plugin.tx_solr {
index {
queue {
<yourindexconfigname> = 1
<yourindexconfigname> {
table = pages
fields {
parentPageTitle_stringS = CONTENT
parentPageTitle_stringS {
# Build a query here to retrieve
# the parent page title.
}
}
}
}
}
}
In your template for search results, you can use the marker ###RESULT_DOCUMENT.parentPageTitle_stringS### to retrieve the field.
The available field types can be found in EXT:solr/Resources/Solr/typo3cores/conf/general_schema_fields.conf from line 157 onwards (refering to version 3.0.0 here).
You should of course use a type other than string if you want to have the result indexed nicely.
