I think, partial searching is working sometimes, like when write first character is entered then search happens. But when two or more characters are write for search purpose searching disappear on the pdf page.

This is an interestingly encoded PDF. The text selection and search code use the same base layout code to determine glyph order. The system property org.icepdf.core.views.page.text.spaceFraction=1 improves the situation a bit but the results still aren't ideal. I'll need to take a closer look to figure out what's happening here withe auto space detection code.

Hi @pcorless, I'm using ice-pdf version com.github.pcorless.icepdf:icepdf-core:7.0.2 and com.github.pcorless.icepdf:icepdf-viewer:7.0.2, other I generated pdf file by itext pdf version com.itextpdf:itextpdf:5.5.13.2

I finally got back to this issue. I have a hunch that the landscape layout is throwing off the text sorting code. This is a really good test case for dealing with text that is layed out using the y coord instead of x.

Sorry I haven't looked at this one in a while. I'll try and make some time for it as I do have some new ideas on how to solve this that came out of the redaction work.
