some advice

HI- I am writing to ask you some advice because I do not know if Eloquent can help me and I expect you will be able to tell me, perhaps the way I already do my work is the most easy way OR perhaps a bible program like eloquent is what I should use.

first: my focus is on the GREEK text- of Old and New Testaments.
I am on the en.katabiblon .com LXX and NT all day.. comparing word use in their lexicon cross references....

so for example
I wanted to see how Ἐγώ εἰμι was used in the NT... who said it when and how it appears in the text.
I clicked on an in-text use of the word εἰμι
a dialog box pops open with the definition and a few links
I open the "lexicon" link (my gold mine)
and this is where my work is done:

the katabiblon "lexicon" link provides me each of the instances of the word in all its possibilities in both testament
its occurrence in the the NT and OT.

Because my work is across testaments, I love this link by lemma and use-
so my question to you is layered:
I do not know if any other resource has this comparison feature
and
would this even be considered a program feature or a module ? I guess the inter-relationship between modules is a function of the program features... so question #1 is: can this type of work even be done on eloquent ?

and if so,
the next question is about the actual material linked on the katabiblon site....
I love how they have the variants marked in the sentance.. if something is missing from NASB it says "NASB -"... this is great info to have within my actual analysis.

Now, there are things lacking in the flexibility of katabiblon- I have to export any of the result and work on them off line- all my notes and queries have to done for myself on my own programs like pages or numbers... so this is where "bible software" would be useful as well...
also I can only search one word at a time...
I can only look up eimi
not
ego eimi
 or
ego gar eimi
or
 eimi ego..

this may be a tedious filtering to do on my own but it is far less of a waste of time than trying out software I can't use.... so I am hoping you will be able to guide me in any thought you have about the matter.
you can write me direct at <email address hidden> because i just joined ubuntu to be able to get your email... I do not even know what ubuntu is...so I may not see a message if it is sent "in house" only .. so please do cc your response to me at <email address hidden>
