- Retrieval by file name, code, keyword, or content: Retrieval of segments according to criteria
- Tabular analysis: constructing tables combining criteria and arranging data in rows and columns
- Construction of linkage hypotheses: looking for relationships across data
- Comparison of cases/files: contrasting coding across files
- Sequential analysis: objective hermeneutics
- Comparison of cases by Boolean analysis: critical features and identification of "types" as introduced by Charles Ragin.

Data context
Data can be directly analyzed on the screen (one-step) or outside (two-steps). One-step allows on-screen coding with digitized data. Two-steps allows the user to enter codes on the screen, keeping the documents on the desk or in other means such as cameras, TVs, etc. For instance, two-steps allows the analysis of recordings, diaries, incunabula, or objects without transcribing, taking photos, or scanning them.[3][4]
Comparison of cases/files by Boolean analysis
Aquad allows comparison of cases/files by "logical minimization", by using its own algorithm and the R package qualitative comparative analysis to determine implicants .[5]
