Struct SearchConfig 

pub struct SearchConfig {
    pub batch_size: usize,
    pub max_tokens: usize,
    pub chunk: ChunkConfig,
    pub text_mode: bool,
    pub cascade_dim: Option<usize>,
    pub file_type: Option<String>,
    pub mode: SearchMode,
}

Runtime configuration for the search pipeline.

All tuning parameters that were previously compile-time constants are gathered here so they can be set from CLI arguments without recompiling.

Fields

batch_size: usize

Chunks per inference call. Larger values amortize call overhead but consume more memory. Default: 32.

max_tokens: usize

Maximum tokens fed to the model per chunk. 0 means no limit. Capping tokens controls inference cost for minified or dense source. BERT attention cost scales linearly with token count, and CLS pooling means the first token’s representation carries most semantic weight. Default: 128 (7.7× faster than 512, with minimal quality loss).

chunk: ChunkConfig

Chunking parameters forwarded to the chunking phase.

text_mode: bool

Force all files to be chunked as plain text (sliding windows only). When false (default), files with recognized extensions use tree-sitter semantic chunking, and unrecognized extensions fall back to sliding windows.

cascade_dim: Option<usize>

MRL cascade pre-filter dimension.

When set, SearchIndex stores a truncated and L2-re-normalized copy of the embedding matrix at this dimension for fast two-phase cascade search. None (default) disables cascade search.

file_type: Option<String>

Optional file type filter (e.g. “rust”, “python”, “js”).

When set, only files matching this type (using ripgrep’s built-in type database) are collected during the walk phase.

mode: SearchMode

Search mode: hybrid (default), semantic, or keyword.
