Error message

Unsupported value type for GTE condition. Only supports Number

What it means

Filter translation guard in QdrantFilterExpressionConverter.buildGteCondition: a GTE (greater-than-or-equal) comparison was given a non-Number right-hand value; only numeric range comparisons are supported.

Solutions

1. Use a numeric value for the GTE comparison

Example fix

// before
Filter.builder().gte("createdAt", "2024-01-01").build();
// after
Filter.builder().gte("createdAt", 1704067200L).build();

static void checkGteOperand(Object v) {
    if (!(v instanceof Number)) {
        throw new IllegalArgumentException("GTE operand must be a Number, got " + (v == null ? "null" : v.getClass()));
    }
}

static boolean isNumber(Object v) {
    return v instanceof Number;
}

try {
    vectorStore.similaritySearch(req);
} catch (RuntimeException ex) {
    if (ex.getMessage() != null && ex.getMessage().contains("GTE condition. Only supports Number")) {
        throw new IllegalArgumentException("GTE requires a numeric operand", ex);
    }
    throw ex;
}

When it happens

Trigger: Filter.builder().gte("rating", "4").build() or gte("year", true) — GTE with a String, Boolean, date, or null right operand.

Common situations: Same family as GT/LT: dates as ISO strings, numbers arriving as strings from web request parameters.
