The Search Engine
Introduction
The whole DAPCA digital infrastructure has been conceived around the concept of token, which constitute the minimal semantic unit into which transliterated cuneiform texts are decomposed during the ingestion process (see also).
While tokens typically correspond to lexical words, the system extends this concept to encompass diverse categories of epigraphic notation, including blank spaces, seal impressions, ruling lines, and other non-textual features that preserve the documentary structure and spatial organization of the original artifacts. Of course, these latter elements are not included into search rusults.
This tokenization strategy provides multiple technical and scholarly advantages. From a computational perspective, token-based indexing enables efficient data management and retrieval across large corpora, supporting complex query operations with minimal latency. The granular representation allows for precise search targeting at the word level while maintaining the capacity to reconstruct higher-level textual structures (sintagmata, phrases, entire paragraphs, documents) dynamically. From a philological perspective, the system preserves the documentary integrity of cuneiform texts by maintaining spatial relationships, epigraphic features, and structural annotations that are essential for scholarly interpretation but often lost in simplified digital representations.
The search interface has been designed specifically for the requirements of Assyriological research, accommodating the distinctive characteristics of cuneiform writing systems while remaining accessible to users with varying levels of technical expertise. This balance between specialized functionality and usability reflects DAPCA's commitment to serving both expert philologists and researchers from adjacent disciplines engaging with cuneiform sources.

Search Syntax
DAPCA search engine is in short an interface to a PostgreSQL databese and its query functions. For the most, it gives access to the full power of the PostgreSQL query language, allowing users to perform more or less complex searches with REGEX.
