進階檢索，從邏輯開始。
留意過全文檢索的小箭頭符號嗎？它是邏輯運算的入口，讓你一次組合多個關鍵字。
為什麼要用「邏輯運算」？
一般搜尋只能輸入單一字串，但是，透過邏輯符號，我們可以告訴系統：哪些詞要靠近、哪些要一起、哪些必須排除……
CBReader 支援七種邏輯運算符號：
|
符號 |
說明 |
例子 |
|
+ |
靠近（不計順序，相距 ≤ 30 字） |
佛陀+buddha |
|
* |
先於（有順序，相距 ≤ 30 字） |
佛陀*buddha |
|
& |
一起（不計順序、字距） |
佛陀&buddha |
|
, |
擇一 |
佛陀,buddha |
|
- |
排除 |
佛陀-佛陀曰 |
|
? |
萬用字元 |
蓮?色 |
|
( ) |
分組（決定優先組合） |
(佛陀*舍利弗),阿難陀 |
請留意：
- 邏輯運算以卷（歷代藏經）或篇章（近代文獻）為基本搜尋單位。
- 使用半形符號（ 如 + & ?），勿用全形符號（如 ＋＆？）。
應用這套邏輯運算，不再只是查找資料——也釐清思路！
From Query to Clarification: Harnessing Logical Operators in CBReader Full-Text Search
Advanced query begins with logic.
Have you noticed the little arrow in the Full-Text Search panel? It leads to logical operation, allowing combination of multiple search strings in a single query.
Why use Logical Operation?
By default, searches are based on one string at a time. However, with a few simple symbols, you can tell the system which terms should appear together, which must be excluded, and how they relate to each other.
Seven Logical Operators in CBReader:
|
Operators |
Function |
Example |
|
+ |
Near (≤ 30 characters) |
佛陀+buddha |
|
* |
Before (A precedes B ≤ 30 characters) |
佛陀*buddha |
|
& |
AND (same fascicle) |
佛陀&buddha |
|
, |
OR (alternative) |
佛陀,buddha |
|
- |
Exclude (eliminate unwanted result) |
佛陀-佛陀曰 |
|
? |
Any (wildcard) |
蓮?色 |
|
( ) |
Precedence (sets priority) |
(佛陀*舍利弗),阿難陀 |
-
Searches run per fascicle (historical texts) or section/chapter (modern works).
-
Use halfwidth symbols, e.g. + & ?, instead of fullwidth ＋＆？.
Applying these logical operators not only enhances data retrieval but also helps clarify and organise thought processes!
