To give an example. Here is a list of suggested words and phrases which students should learn: Primary Stage - Levels 1, 2, 3, 4 (P1, P2, P3, P4) (The Portal of National Curriculum, Georgia; Creative Commons License).
I'm looking for a search software that would look through different online texts (novels, news, poems, you name it) and find ones where most of the words are present (well, not all words from that page, say I make sub-list of 30 words).
Additional features that would be great to have:
- Filter text by readability index.
- Chose the type of medium (text, audio, video).
