Content Search: `doc` parameter must match the original filename minus extension

[markpbaggett]

For fulltext/inside.php requests, the doc parameter must match the original filename minus extension.

For instance, this item is called gray-diary but the original filename is GrayDiary.pdf.

Currently, we make a request like:

https://ia601306.us.archive.org/fulltext/inside.php?item_id=gray-diary&doc=graydiary&path=/33/items/gray-diary&q=manufacturing

That returns an error like:

{"error": "No hOCR or Abbyy file present"}

If we take the value of the filename at index 0 and remove the extension, we get the matching results:

https://ia601306.us.archive.org/fulltext/inside.php?item_id=gray-diary&doc=GrayDiary&path=/33/items/gray-diary&q=manufacturing

Adding this as something we should also look at:

If a "book" or "text" work is not a PDF but a work made up of multiple files (TIFFs, JPGs, JP2s), I believe doc will need to reference the filename. We should create a sample work to test this.
