# index_section {#index-section}

Points out the section where an entry in index_phash belongs.

## phash {#index-section-phash}

<!-- TODO: no Markdown rendering for "versionchanged" -->

The field has been transformed to a varchar field, full md5 hashes are
stored.

-   **Field**

    phash

-   **Description**

    The md5 hash of the indexed document.

## phash_t3 {#index-section-phash-t3}

<!-- TODO: no Markdown rendering for "versionchanged" -->

The field has been transformed to a varchar field, full md5 hashes are
stored.

-   **Field**

    phash_t3

-   **Description**

    The md5 hash of the "parent" TYPO3 page of the indexed document.

    If the "document" being indexed is a TYPO3 page, then phash and
    phash_t3 are the same.

    But if the document is an external file (PDF, Word etc) which are
    found as a LINK on a TYPO3 page, then this phash_t3 points to the
    phash of that TYPO3 page. Normally it goes like this when indexing: 1)
    The TYPO3 document is indexed (this has a phash-value of course), then
    2\) if any external files are found on the page, they are indexed as
    well AND their phash_t3 will become the phash of the TYPO3 page they
    were on.

    The significance of this value is that indexed external files may have
    more than one record in "index_section" (with the same phash), a
    record for each parent page where a link to the document was found!
    There are details about this in the section of this document that
    describes the complexities of indexing pages.
