    Searches Court of Cassation (Yargıtay) decisions using the primary official API.

    The Court of Cassation (Yargıtay) is Turkey's highest court for civil and criminal matters,
    equivalent to a Supreme Court. This tool provides access to the most comprehensive database
    of supreme court precedents with advanced search capabilities and filtering options.

    Key Features:
    • Advanced search operators (AND, OR, wildcards, exclusions)
    • Chamber filtering: 52 options (23 Civil (Hukuk) + 23 Criminal (Ceza) + General Assemblies (Genel Kurullar))
    • Date range filtering with DD.MM.YYYY format
    • Case number filtering (Case No (Esas No) and Decision No (Karar No))
    • Pagination support (1-100 results per page)
    • Multiple sorting options (by case number, decision number, date)

    SEARCH SYNTAX GUIDE:
    • Words with spaces: OR search ("property share" finds ANY of the words)
    • "Quotes": Exact phrase search ("property share" finds exact phrase)
    • Plus sign (+): AND search (property+share requires both words)
    • Asterisk (*): Wildcard (construct* matches variations)
    • Minus sign (-): Exclude terms (avoid unwanted results)

    Common Search Patterns:
    • Simple OR: property share (finds ~523K results)
    • Exact phrase: "property share" (finds ~22K results)
    • Multiple required: +"property share" +"annulment reason (bozma sebebi)" (finds ~234 results)
    • Wildcard expansion: construct* (matches construction, constructive, etc.)
    • Exclude unwanted: +"property share" -"construction contract"

    Use cases:
    • Research supreme court precedents and legal principles
    • Find decisions from specific chambers (Civil (Hukuk) vs Criminal (Ceza))
    • Search for interpretations of specific legal concepts
    • Analyze court reasoning on complex legal issues
    • Track legal developments over time periods
