Storing, and retrieving the coordinates from Solr will likely be
faster than from the database. However, I still think that you
should think more carefully about your use case of highlighting
the images. It can be done, but is a significant amount of work,
and will need storage, and computational resources.
1. For highlighting in the image, you will need to store two sets
of coordinates (e.g., top right and bottom left corners) as you
not know the length of the word in the image. Thus, say with
15 words per line, 50 lines per page, 100 pages per document,
you will need to store:
4 x 15 x 50 x 100 = 3,00,000 coordinates/document
2. Also, how are you going to get the coordinates in the first
place?
