Hi Chris,
If there are a large number of PDF files need to be indexed, when the
catalog was initially created, the PDF file will appear in the search list,
but the abstract was not displayed. This is a expected behvaior. Generally
the abstract will show up a couple of hours later.
The first step in indexing is to scan the files, which produces a list of
files to filter. Once the files are scanned, the name, filetype, size are
known. The Cidaemon process is called for the files in this list, the
Ifilter is loaded, and the content is filtered. If this fails for some
reason or is deferred for retrying later because the file is in use, the
file will show up as unfiltered. Unfiltered docs can still be located by a
#filename search or a @size search.
After the generate abstracts option is set, the files must be rescanned.
If CiForceUsCi is set to true, then Index Server will use the index even if
it is out of date, so old data could be returned while the rescan is in
progress.
If the indexing performance adjustment is not set to Instant, it will took
a while to filter the PDF documents and create the abstracts.
Indexing Service Catalog Updates Take Several Hours or Days to Show Changes

Generating an abstract will use more CPU time during the indexing process.
More disk space will also be used for the corpus. By default, abstract
creation is disabled on Windows 2003 Index Server. In order for the
abstract information to be generated and returned, Abstract generation must
be enabled and the characterization property must be cached.
Abstract generation can be set at the Index Service level and inherited by
catalogs, and can be overridden at the catalog level.
1) Run the Index Server MMC.
2) Right-click on Indexing Service, and then select Properties. Click on
the Generation tab. Check the "Generate abstracts" option to enable this
for all catalogs.
3) Right-click on a catalog and select Properties. Click on the Generation
tab. If the "Inherit above settings from Service" option is checked, then
the Indexing Service settings will be used. Otherwise, check the "Generate
abstracts" option.
Use the following procedure to enable caching of the characterization
property.
1) Run the Index Server MMC.
2) Expand the Index Service. Expand a catalog. Click on the properties
folder.
3) Locate the property that has a Friendly Name of characterization.
Right-click on characterization and select Properties.
4) Check the box labeled Cached. Set the datatype to VT_LPWSTR.
After making the above changes, restart the Indexing Service, and perform a
Full Rescan of the directories associated with the catalog.
Also please note Microsoft does not provide support for 3rd party software.
You will need to contact Adobe regarding the PDF Ifilter. As I know,
abstract should be supported by the lastest PDF Ifilter. Please verify that
you have the latest version of the Ifilter installed.
