The search index we build in this application is specifically geared toward blog posts. In a larger web application, you may have other content you want to index also. In that instance you may want to have one index for each type of data (then when a search is performed, you search each index), or you have one index containing all searchable data. Each of these methods has its own advantages and disadvantages. For example, if you use a single index for all types of data It is simpler to search across all indexes in one operation since all searchable data is in one place. You must keep track of the kind of data each document in the index is. For example, if you are indexing data about news articles as well as about uploaded files, you must differentiate between these somehow when you display search results to users. On the other hand, if you use one index for each type of data It is more difficult to search because you have to search every index when a search is performed. It gives you more leverage to create different types of searches on your site. For example, if you want a form to allow users to search only in uploaded files, then you simply search the corresponding index. If you also have an index that holds information about news articles, you can skip searching this completely. Ultimately it comes down to your own needs, depending on the type of application you are implementing and the search capabilities you need to provide.

As mentioned earlier this chapter, each entry in a Zend_Search_Lucene index is referred to as a document. To create a document that can be added to a search index, we use the Zend_Search_ Lucene_Document class. After instantiating this class, we add all of the required fields and data accordingly. Once this has been done, the document can be added to the index. In this section, we will write a new function for the DatabaseObject_BlogPost class that builds and returns such a document. We are not actually concerned with adding this document to the search index yet. We will deal with this later this chapter.

Listing 12-1 shows the beginning of the getIndexableDocument() method we add to the BlogPostphp file (in the /include/DatabaseObject directory) Listing 12-1 Creating the Indexable Document (BlogPostphp) < php class DatabaseObject_BlogPost extends DatabaseObject { // .. other code public function getIndexableDocument() { $doc = new Zend_Search_Lucene_Document(); $doc->addField(Zend_Search_Lucene_Field::Keyword('post_id', $this->getId())); After instantiating the Zend_Search_Lucene_Document class, we add a field to hold the ID of the blog post Each document in the index will have its own internal ID; however, we are not able to set this ourselves, so we must still store the relevant blog post ID from our database In the previous section, we looked at the five different types of fields we can add to an indexable document There is a static method in the Zend_Search_Lucene_Field class for each of these types This creates an object compatible with the addField() method.

end end end hpricot_doc = Hpricot.XML(ARGF) rows = (hpricot_doc/"rows/row") rows.each do |row| AdResult.new do |n| row.attributes.each do |attribute_name, attribute_value| n.send("#{attribute_name}=", attribute_value) end n.save end end

The name of the field is the first argument, while its value is the second argument In the post_id field we use the Keyword type These are the reasons we use this type: We want to retrieve the document from the index later using this ID (that is, we want to search on this ID) We want to retrieve the ID from any search results so the database data can be loaded accordingly It is not textual data that needs to be tokenized (therefore ruling out the Text type) Next we must add the data we want users to be able to search on to this document Since we want to search on this data but we don t need to store it in the index (since we will retrieve the found blog posts from the database), we can use the UnStored field type.
