LHelp loads index only for first chm, but why?

[Andrey Sobol]

If I set ON - "load all chm in single tab".
I see that into unit chmcontentprovider line 587, but why?

    // we fill the index here too but only for the main file
    if fChms.IndexOfObject(CHMReader) < 1 then             

May be that is only for to do later?
Can anyone to say more?

I have made first version of a redone. A combine of all indexes from the lazarus chm directory takes 1.5 sec. I think that is fine. It is with sorting the entire index tree by top level.

That's about right, that is how long it takes the textmode IDE too.

You can /MAYBE/ shave off some time by keeping everything widestring.

I see you last worked with CHM packages...
May be you will fix my patch?

The patch for indexes combining was placed.

Note that it would be much faster to combine the binary indexes. (basically a merged of b+trees, at worst a merge sort).

Code for that would be nice in package chm, to keep it IDE independent.  In theory you could write out that combined index even, there is even a (MS) extension for that; .CHW which is a modified chm variant.

I think about that, but now we have nothing.
